Vertical Multistage Fire Pump

1.Introduction:

CDL/CDLF high pressure water pump is special in high pressure, made of stainless steel 304 or 316, all parts touch with liquid are of stainless steel. The pump is vertical non-self priming multistage centrifugal pump, which drived by a standard electric motor.The motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylingder and flow passagecomponets are fixed between pump head and inlet and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.

2.Applications:

· Urban water supply and pressure boosting

· Industrial circulating system and processing system

· Water supply for boiler, condensing system, high-rise building or fire fighting system.

· Water treatment and RO system

· Cooling water system

3.Electric motor:

· TEFC motor,

· 50HZ or 60HZ 220V or 380V

· Protection class: IP55, Insulation class: F

4. Operation conditions:

Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers

medium temperature: -15°c~+120°c

Capacity range: 1~180 m³^_/h

Head range: 6~305 m

Q: does anyone know how to remove the water pump on an 84 corvette its killing me: The easiest way is from underneath the car . Loosen the nuts on the pulley first then remove the belt and the rest should be easy from there .

Q: what size and what type water pump do i need?i am wanting to pump water from a river 345'-0 up hill at 45deg angle. i would like the water pump located at the cabin where the water dispursement would be. is there a pump that would allow me to do this. also, what size piping should i run from the river to the cabin. i can fabricate my own collection box at the river.any suggestions would be appreciated.: 7 hp motor 8 IMPERIAL head pump( will through about 400 ft up ) with 50 mm piping will work for you.

Q: I was wonder if there is a water pump in the out drive, my boat is overheating we are think it could have something to do with the water pump: The water pump is located in the outdrive. You should see a screen area on the lower end where the pump is loicated. I would guess the impeller needs to be replaced. You should stop running the engine 'till it is fixed.

Q: 50 meters deep well with what water pump: home?: For deepwater submersible pumps, ordinary submersible pumps are inefficient.

Q: Hello everyone, is the general household deep well pump capacitor how to pick up ah, 220V voltage, a capacitor, capacitor, there are 2 lines, but the motor is 3 lines, how can I put these 7 lines together?.Please don't copy professional theories from others.: 220V has two lines (lines 1, lines 2)There are two lines of capacitance (line 3, line 4)There are three lines on the motor (line 5, line 6, line 7)3 11 52 64 7That's plain enough. To change the turn, change any two of the 5, 6, 7, three lines

Q: Who knows? Is the motor with a pump a squirrel cage induction motor?: Should be a squirrel cage motor for winding asynchronous motor for high torque applications. For example, its structure and the hoist crane cage motor with different rotor loop it can slip ring external resistor. The motor rotor circuit principle know that certain external resistance can reduce the starting current, but also can improve the rotor circuit power factor and torque. The pump load does not need large torque. So it should be the squirrel cage induction motor.

Q: how to replace water pump 97 pontiac bonneville?: There's okorder /

Q: I'm going to buy a pump to take water from a lake and use it to water the grass at my cottage. I would like to run at least 2 hoses at the same time. I'm looking at one that's 3/4 horse. Is this too small? The yard is a little more than an acre.: A 3/4 horse pump usually has a one inch suction and 3/4 inch outlet and is more than enough to water one acre. Remember, you don't have to water every day or even cover the entire acre all in one day. The industrial/agricultural pump mentioned before (4 inch? 6 inch? Or more?) is intended for use on dozens of acres per day.

Q: First I need to take off the belt, remove power steering pump, remove water pump bolts (the bolts are various length), remove water pump pulley (from old pump), install pulley on new pump, install new pump (with gasket and bolts in the right holes), install power steering pump, install belt. Is this the correct order? Can somebody throw any tips at me (somebody who has done it on this vehicle). It's a 2001 WJ with a 4L.: The centrifugal pump is the most popular water pump in mining industry, it’s could be driven by the electric motor or by diesel engine. This water pump consist shell, impeller, and flange. It gets the advantages of simple structure, easy for maintenance, with high capacity and high lift meter. Application: The centrifugal pump is widely used in mining, coal, metallurgy, building material industry, and other industries which need transfer water or other liquid.

Q: What do water pumps do on a car?: the pump circulates the water throught the cooling system. when they fail the engine will overheat... but keep in mind you have other parts that work in conjuction with the pump like the thermostat which opens and closes at certain temps to keep the coolant at the proper working temp so the car runs correclty...if a thermostat fails and is stuck closed you can overheat also or if stuck open then the coolant may run to cool and the car may not run at its best. good luck
