This series is a horizontal, single suction and multi-stage centrifugal pump, which adopts the hydraulic model of efficient and energy-saving products recommended by the sate, playing a leading technical role in the industry. It has such advantages as high efficiency, wide performance range, safe and stable operation, low noise, long life and easy installation and maintenance.

  It can be used to transport clear water without solid particles (grinding materials) or suspended substances or other liquids with similar physical and chemical properties as clear water. It can also transport hot water, oil products, corrosive or abrasive media and so on by means of changing the pump’s material (or the material of the pump’s flow-through part) and sealing mode and adding a cooling system.

  Our company has passed the certification of IS9001:2000 International Quality Management System. Our product design, production and service are provided with strict and standard control systems and our product quality is fully guaranteed.

By its application scope, the horizontal multi-stage centrifugal pump includes the following types:   D pump can be used to transport clear water containing no solid particles with a temperature lower than 80℃ or liquids with similar physical and chemical properties as clear water. It’s applicable for water supply and drainage works in mines, plants and cities.

  DF pump can be used to transport corrosive liquids containing no solid particles with a temperature range of -20℃~105℃. The pump’s allowable inlet pressure shall be less than 0.6MPa.
  DY pump can be used to transport oil and petroleum products containing no solid particles with a temperature range of -20℃~105℃ and a viscosity less than 120cP.

  DG horizontal single-suction multi-stage centrifugal pump can be used to transport the clear water or other liquids with similar physical and chemical properties as clear water. It’s applicable for the water supply in low/middle/sub-high pressure boilers as well as for the high-pressure water supply and drainage in plants or cities. The temperature range of transported medium is -20℃~105℃; And the allowable inlet pressure shall be less than 0.6MPa.

  In addition, our company can provide this pump series’ multi-outlet structure and function as required by customers. The user can select the pump’s material, sealing mode, structure, motor capacity and so on in a reasonable way in concentration, specific gravity and working temperature, the pump’s inlet pressure and so forth.

Q:93 Cutless Sierra FWD
It's a major job involving the belt tensioner and quite a few other hard to get at parts as the water pump is buried against the side of the engine compartment. But if you want to try it borrow from the library or buy a Chilton's or any popular service manual and follow the directions (STEP BY STEP),good luck
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.
that is a trick question, because you didnt mention the size of hose you will be using. and i would suggest asking the people at the place you are going to purching the pump,because you may have to have MORE POWER to pump it at a great distance. I really dont think this help you but ask the people who really works in this field.
Q:Hoping that someone may read this.Broke down yesterday after re-filling coolant when car re-heated and mechanic who rescued us advised that the water pump is leaking and requires replacement.Our local garage have advised that to change the water pump also requires a new camber (?) kit and including both and 3.5 hours labour their total quote is ?315.08.This sounds crazy for changing a water pump - can anyone shed any light and reckon that they may be taking the mickey?Am not technical so wouldn't attempt to do work myself, however if we go back to garage, or to others, I'd like to know exactly what work needs doing.Thanks!
I've had 2 Mondeo 1.8s, both water pumps have failed. The fact is, they're cheap, crap cars it's Russian roulette as to when they'll fail. My first went at around 90,000 miles, but the car was second hand I don't know if it had been changed before, the second one failed at 60,000 with a full history. There's no warning, they just go - no leaking, just temperature off the gauge engine cuts out.
Q:What are the conditions for the series and parallel connection of the pumps?
Water pumps in series require equal flow, and the latter should be able to withstand the pressure of two pumps and.The parallel pump requires the pump with equal lift head, and the outlet pipe in parallel shall be chosen according to the flow rate of two pumps.
Q:The garage told me my water pump was pumping quot;weaklyand needs to be replaced.
Yes you can have a weak pump. They wear out after awhile. but before replacing the pump, make sure that you don't have any blockage in you hoses. A partially blocked hose can make it appear like your pump is not working well and cleaning a hose out is a lot cheaper then replacing the pump.
Q:the pump is pumping hot wtaer from the hot water tank around the domestic hot water system, i.e to taps and shower.
Depends on the type of pump, but for your garden variety type pump, there is a impeller of some sort that is turned by the motor to pump the water. The actual shaft of the motor is not in contact with the water (except where the impeller is attached to the shaft). A common type of failure mode here is when the seals on the shaft (which keep the water contained to the impeller area) have failed and water has gotten past the shaft seal and degraded the bearings holding the shaft = seizing up.
Q:The role of impeller in water pump
Pump impeller through the motor to drive rotation, so that the medium (water) by centrifugal force or lifting force, so that the medium has mechanical energy (kinetic energy)
Q:My friend wants to buy a 90's somethin dodge avenger.( not sure what year) and the guy says the water pump is bad. Does the car have to be re timed when u replace the water pump?
Yep, but it's not as bad as you would think, but bad enough to take a weekend.
Q:Fire pump control cabinet installation distance, ground height should be how much?
The ground height shall be determined according to the height of the connecting line at the bottom of the control cabinet and the water pump, usually 15~20CM.
Q:Variable flow variable frequency water pump how to adjust the flow?
Variable frequency pump is mainly depending on the frequency converter to adjust the speed of the pump motor, thereby regulating the flow and lift pump, the following Q1/Q2=n1/n2; H1/H2= (n1/n2) -, the frequency range of the frequency converter in 30HZ~50HZ
