Kanur Fire Fighting Truck Tanker

This standard defines the requirements for new automotive fire apparatus and trailers designed to be used under emergency conditions to transport personnel and equipment and to support the suppression of fires and mitigation of other hazardous situations.

Mobile water supply apparatuses.

They bring a source of water to fire scenes that may lack adequate water supply.

Fill & dump rates

The NFPA standard for tankers/tenders states that these apparatus must be capable of being filled at a rate of 1,000 gpm and must be able to be emptied or dumped at the same rate of 1,000 gpm, at a minimum. How can you check your tanker/tender to ensure this kind of performance? Well, it is pretty easy. If you have a 3,000-gpm tanker/tender and a watch, then you just have to time it. If you can fill and dump the apparatus within 3 minutes or less, than you’ve met the standard.

How can you check to make sure that your 3,000-gallon tanker/tender is actually dumping 3,000 gallons of water? First, make sure that the apparatus tank is completely full. Next, take the vehicle and get it weighed. Then dump all the water that you can and weigh the truck again. Water weighs 8.34 pounds per gallon, so if you have a 3,000-gallon tank, then the apparatus must weigh 25,020 pounds less than the initial weight.

Check the weight

With new tanker/tenders, it is extremely important that the apparatus is delivered to you completely empty and with all the equipment and a full tank of fuel. This is when and how to weigh the vehicle. You then need to fill the water tank and weigh it again, and then dump the water tank and weigh it again. Two items you can now check off your delivery acceptance list—that the vehicle is not overweight and that the vehicle is dumping the rated capacity of the tank.

As you are filling and dumping the tank, it is advisable as part of the acceptance testing to time it to make sure that the apparatus can meet the NFPA standard of dumping and loading at a rate of at least 1,000 gpm.

Get what you paid for

Many fire departments are not doing any kind of acceptance testing upon delivery. This is a big mistake. The NFPA standard has acceptance requirements for all kinds of apparatus. If you find that you have a 1,500-gpm pump that, upon delivery, cannot deliver that required flow, then you can send the unit back to the manufacturer and the unit can be fixed under warranty. However, if you wait until the first in-service pump testing, the unit may be out of warranty and the fire department may have to pay for any repairs. The key here is to make sure you are getting what you paid for.

Inductive Pump

Mechanical pumps may be submerged in the fluid they are pumping or be placed external to the fluid.

Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps. In centrifugal pumps the direction of flow of the fluid changes by ninety degrees as it flows over an impeller, while in axial flow pumps the direction of flow is unchanged.

Positive-displacement pumps

Lobe pump internals A positive-displacement pump makes a fluid move by trapping a fixed amount and forcing (displacing) that trapped volume into the discharge pipe. Some positive-displacement pumps use an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant through each cycle of operation.

Positive-displacement pump behavior and safety

Positive-displacement pumps, unlike centrifugal, can theoretically produce the same flow at a given speed (rpm) no matter what the discharge pressure. Thus, positive-displacement pumps are constant flow machines. However, a slight increase in internal leakage as the pressure increases prevents a truly constant flow rate.

A positive-displacement pump must not operate against a closed valve on the discharge side of the pump, because it has no shutoff head like centrifugal pumps. A positive-displacement pump operating against a closed discharge valve continues to produce flow and the pressure in the discharge line increases until the line bursts, the pump is severely damaged, or both.

Positive-displacement types

A positive-displacement pump can be further classified according to the mechanism used to move the fluid:

Rotary-type positive displacement: internal or external gear pump, screw pump, lobe pump, shuttle block, flexible vane or sliding vane, circumferential piston, flexible impeller, helical twisted roots (e.g. the Wendelkolben pump) or liquid-ring pumps
Reciprocating-type positive displacement: piston pumps, plunger pumps or diaphragm pumps
Linear-type positive displacement: rope pumps and chain pumps

A gear pump uses the meshing of gears to pump fluid by displacement. They are one of the most common types of pumps for hydraulic fluid power applications. The gear pump was invented around of year 1600.

Gear pumps are also widely used in chemical installations to pump high viscosity fluids. There are two main variations: external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear (internal spur gear teeth face inwards, see below). Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either a motor or a pump.

As the gears rotate they separate on the intake side of the pump, creating a void and suction which is filled by fluid. The fluid is carried by the gears to the discharge side of the pump, where the meshing of the gears displaces the fluid. The mechanical clearances are small— in the order of 10 μm. The tight clearances, along with the speed of rotation, effectively prevent the fluid from leaking backwards.

The rigid design of the gears and houses allow for very high pressures and the ability to pump highly viscous fluids.

Many variations exist, including helical and herringbone gear sets (instead of spur gears), lobe shaped rotors similar to Roots blowers (commonly used as superchargers), and mechanical designs that allow the stacking of pumps. The most common variations are shown below (the drive gear is shown blue and the idler is shown purple).

Applications

Petrochemicals: Pure or filled bitumen, pitch, diesel oil, crude oil, lube oil etc.
Chemicals: Sodium silicate, acids, plastics, mixed chemicals, isocyanates etc.
Paint and ink.
Resins and adhesives.
Pulp and paper: acid, soap, lye, black liquor, kaolin, lime, latex, sludge etc.
Food: Chocolate, cacao butter, fillers, sugar, vegetable fats and oils, molasses, animal food etc.

Rotary positive-displacement pumps fall into 5 main types:

Gear pumps – a simple type of rotary pump where the liquid is pushed around a pair of gears.
Screw pumps – the shape of the internals of this pump is usually two screws turning against each other to pump the liquid
Rotary vane pumps
Hollow disk pumps (also known as eccentric disc pumps or Hollow rotary disc pumps).
Vibratory pumps or vibration pumps

Water Pump

The pumping of water is a basic and practical technique, far more practical than scooping it up with one’s hands or lifting it in a hand-held bucket. This is true whether the water is drawn from a fresh source, moved to a needed location, purified, or used for irrigation, washing, or sewage treatment, or for evacuating water from an undesirable location. Regardless of the outcome, the energy required to pump water is an extremely demanding component of water consumption. All other processes depend on or benefit either from water descending from a higher elevation or some pressurized plumbing system.

The ancient concept of the aqueduct took simple and eloquent advantage of maintaining elevation of water for as long and far a distance as possible. Thus, as water moves over great distances, it retains a larger component of its potential energy by spending small portions of this energy flowing down a slight gradation. A useful aqueduct system ultimately depends on a fresh water source existing at a higher elevation than the location where the water can be of use. Gravity does all the work. In all other instances, pumps are necessary.

In day-to-day situations, available water is often contaminated, unhealthy, or even naturally poisonous, so that it is necessary to pump potable water from lower levels to higher levels, where it can be of use. A fresh water source in a lower stream, river, pond, or lake is often pumped to higher ground for irrigation, livestock, cooking, cleaning or other uses by humans, who quite naturally need fresh water. This will purify mostly fresh water, and the treatment of largely contaminated water refer endlessly to pumping.

A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action, typically converted from electrical energy into hydraulic energy. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps.

Pumps operate by some mechanism (typically reciprocating or rotary) and consume energy to perform mechanical work moving the fluid. Pumps operate via many energy sources, including manual operation, electricity, engines, or wind power, and come in many sizes, from microscopic for use in medical applications, to large industrial pumps.

Mechanical pumps serve in a wide range of applications such as pumping water from wells, aquarium filtering, pond filtering and aeration, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers and other components of heating, ventilation and air conditioning systems. In the medical industry, pumps are used for biochemical processes in developing and manufacturing medicine, and as artificial replacements for body parts, in particular the artificial heart and penile prosthesis.

When a casing contains only one revolving impeller, it is called a single-stage pump. When a casing contains two or more revolving impellers, it is called a double- or multi-stage pump.

In biology, many different types of chemical and biomechanical pumps have evolved; biomimicry is sometimes used in developing new types of mechanical pumps.

Village Level Operation and Maintenance (VLOM) is an unofficial classification given to handpumps used in developing countries that require minimal maintenance or that can be done “at the village level.” Not all maintenance and repair need to be done by the villagers for a pump to be classed as a VLOM pump. VLOMM, or Village Level Operation and Management of Maintenance is often used synonymously. This addition emphasizes the role of users as the managers of maintenance able choose to use someone from outside the village to assist with more complicated repairs.

Split Case Pump
