General Description
The type LW pump is single-stage single-suction vertical volute centrifugal clear water pump. It is widely used to handling circulation water for power stations, mining drainage as well as water supply & drainage of municipal facilities and farmlands. It is provided for delivering clear water without solid particles or other liquid which is physically and chemically similar to clear water. The highest temperature of the liquid must below 50℃.
Performance range
Capacity Q: 1.6~6.8m3/s
Head H: 13.1~63m
Instruction of pump type
For example LW44P Left-11JA
LW—Large scale vertical single-stage single-suction volute centrifugal pump.
44— inlet diameter 44 inch.
P—the pump foundation plate is changed
Left—the rotation of impeller is clockwise looking from the motor to the pump.No indication when the rotation of impeller is counter clockwise.
22—the number obtained from the pump specific speed divided by 10.
I—Difference of impeller in construction, indicating Ⅰ, Ⅱ…… .
A—Outer diameter of impeller has bee changed. Indicating A, B, C…….
Structure
*The pump is vertically installed with the inlet vertical downward and the outlet horizontal extending.
*The pump and the motor are connected directly and mounted on one concrete foundation.
* The seal usually uses packing seal.
*The pump adopts rolling bearings.
*The impeller has construction of balancing rib.
* The axial force is carried by the motor.
The direction of rotation
The rotation of pump rotor is counter clockwise looking from the motor to the pump. Indicating “left” in pump type if you require the rotation of pump rotor is clockwise .Both rotation mode have same performance data.

- Q: What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
- The feed water pump is the water pump for the entire boiler, and the water needed by the boiler is supplied by a feed pumpThe condensate pump is supplied to the deaerator after condensing the condensate from the turbineVacuum pump water jet pump should be said, to ensure the turbine vacuum pumpThe low drain pump is the power pump of the low temperature heater
- Q: From the days of the laying of pipe line and trouble is far away, two or more people share the idea of a water pump, controlled by the electromagnetic valve, do not know whether it is feasible, attention should be paid to each of the power may be different phase, and it is the automatic control, automatic switching request all big brother big sister what the solution of power. At the same time, the electromagnetic valve is closed to others. Turn on your own solenoid valve StopThe idea is that each pumping with its own power, so you don't have to worry about sharing electricity.
- Each contactor is connected with each power source in the main circuit, and the lower port is connected to the water pump;Control loop, only draw the wiring diagram of A households, households in other similar first power through the control switch in series contactor several other a normally closed contact and then enter the M contactor coil;In water, leading to various water pipes connected with the electromagnetic valve, and the solenoid valve are connected in series and the two contactor normally open contact is connected to the power supply;As long as one of the closed control switch, the pump will run at the same time, using his own power, and this is the other an open pump closed control switch of their own, will not work, the water will not go into his house, the family will not run electricity; only when the first home after closing the control switch second, if still closed control switch, water and electricity will automatically turn to him.Not understood, of course, that there is one drawback, if one is using a pump, a few other can not be used to solve the problems, it is not difficult, is that every installation of a water tank or like a floor, said each install a pressure tank on it
- Q: I have a 1999 Chrysler LHS. Recently, the water pump started leaking and it ruined the timing belt. I brought it to a mechanic that I've never used before, so I have no idea how reliable they are. They now told me that my brake lines blew. Can the leaking water pump also cause brake lines to rot?
- i doubt that the antifreeze would make the brake lines leak ! those are steel brake lines and if they can stand up against road salt then antifreeze won,t hurt them ! if a brake line started to leak then it was rotted !
- Q: Variable flow variable frequency water pump how to adjust the flow?
- Flow plus transmitter control
- Q: Where is the water pump located in a 1995 Toyota tacoma pick up truck. Please be as specific as possible as the the location of the pump. Like what is it undwr or next to...etc
- Pictures at links
- Q: The water hose hooks from the radiator to the water pump. Does an o-ring go in it? What else could be causing it to leak?
- no 0-ring in it ! you either need a new clamp or hose. the cord is probably broke in yours.
- Q: I Need a water pump, no matter its fountain pump or high stream pump. But the things or you can say the parameters i required in that pump is, 2 inch minimum outlet from where the water come out, pressure 130 or above (in PSI) runs wid a 1 or 2 Horse Powered motor not more then 2HP. And the pressure calculation is flow of the water (130 Psi) , like while water is streaming out.Any one who can sugest some water pumps which can fulfill or near or above to my requirements. thanks alot sir for you kind time.
- With 100M of 'head' you're going to need a constant displacement pump, and high pressure piping. I'd consider an intermediate lift station.
- Q: And my heater works 80 % of the time, Is it still ok to drive if I keep putting water in it?
- most water pumps have a weep hole in the bottom of the pump when the seal goes its because the bearing is going bad. As long as the bearing keeps going you have a chance the problem is if the bearing freezes up it just goes BANG ! AND BLOWS ITSELF OFF THE CAR DAMAGING WHATEVER IT HITS ON THE WAY OUT. better safe than sorry a water pump is not that expensive compared to the damage it can cause if the fan locks and shatters too.
- Q: How do you remove the water pump from bmw m42 engine?
- Follow the instruction manual Drain the water first then remove the timing case release the tension from the belt, unbolt it and remove.
- Q: I have a bad water pump on my golf gti.Engine is 2.0L. I just would like to know how hard is it to do it myself. And also is there some special tools that I need.How much time usually takes to get this done? Thank you
- the water pump is external to the engine, no need to touch timing belt unless your changing it, tools needed- 13mm wrench-22mm wrench - 1/4 drive ratchet-10mm 1/4 drive socket- 3/8 drive ratchet- 12mm 3/8 drive Socket-13mm 3/8 drive socket-19mm 3/8 drive socket-16mm 3/8 drive socket 3/8 drive Extension-pliers- flat blade screw driver- 6mm 3/8 drive allen socket--- remove drive belt's- remove p/s pump, a/c compressor( do not disconnect either they will move out of the way)- remove alternator(disconnect battery first)- remove the bracket assembly( four 13mm nuts three hidden in the holes) there is the water pump(two 19mm tall bolts with studs hold it down, 10mm T bolt passes through the timing cover)
