Product Description:

Features of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  ◆ Wide application, it can be used for conveying of flowing materials, even non-flowing materials
  ◆ Continuous conveying, small pulsating quantity
  ◆ The media is not stirred in the pump and is free from squeezing and cutting
  ◆ The flow is in direct proportion to the rotating speed, variable output, measurement feeding
  ◆Elastic stator, certain abrasion resistance


Conveying Medium of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  ◆ Various viscous media (the highest viscosity reaches 106 mm2/s)
  ◆ Fluids with various concentrations and dewatered and dried materials
  ◆ The media containing solid particles, fibers and suspended solids


Multiple Configurations of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  ◆ Materials: The parts can be made from different kinds of metals and rubber materials
  ◆ Drive: Motor speed reduction, motor speed regulation, mechanical speed regulation



  ◆Are CNBM pumps available in DIY stores?

Yes, currently, we’re available for DIY stores all over the world.

  ◆Where do I have to send pumps for service?

You must send them to the CNBM PUMP Service Point or, after contacting Customer Care, to the CNBM PUMP service center in China.

  ◆Are your pumps acid-proofed?

To choose the right pumps for chemical applications, we do need further details on hydraulic operations as well as on the type, concentration and temperature of the liquid.

  ◆Can your pumps mount Eff.1 motors

Currently, only on request though this will shortly be a CNBM standard.

Q:Car still overheating with a new water pump, thermostat?
If your fan is operating.. check to see if the water is circulating. Leave the cap off the radiator and bring up to temp..If it is not, you may have a vapor lock in the system, and will have to bleed the air out.
Q:will a electric generator work in a water pump?
if it is powerful enough to power the pump then yes.
Q:Water pump problem - physics?
IF the pump can produce a static pressure of 8.5e+5 Pa, then it can support a column of water, h h = P/(rho*g) = 8.5e+5/(1000*9.8) = 86.7 m h = 87m Now, the water will have no velocity, so you can't use it effectively, but that's not what the problem asks!
Q:replaced my water pump?
Could be the check valve in your holding tank is allowing it to bleed the pressure back into the well thru the pump and once the pressure regulator drops to cut-in press the pump runs. Get a chair and watch the pressure gage.
Q:what is a submersible well pump?
It is exactly what it sounds like-a water pump that you put in your well under water. It pumps the water into the house directly from the well, and uses the water as a coolant. Usually they are about 18-24 inches long, about 3-5 inches around, and weight about 40 pounds; and cost a small fortune (if you ask me anyway). Depending upon who you ask they are also the most efficient way to get the water from your well to the house, and do not need anywhere near as much servicing as above ground or in-house pump. Ask your local pump dealer which pump is best for you and the needs of your household-they should be able to give you several to choose from.
Q:What is called soft start of water pump?
Soft start has many methods, mainly used in high-power motor.Through soft starter, or frequency conversion start, or star triangle start to achieve.It means that it starts at a slower pace.
Q:What does 'MCL' Unit stands for water pump.?
What Does Mlc Stand For
Q:How do I quiet a noisy water well pump?
It sounds to me like water hammer. There are a few ways to address it, probably the easiest is to add an expansion tank. To find out, try connecting a garden hose somewhere in the system, preferably a cold water pipe. Drain all the water from the hose and put a nozzle or plug on the end so the air can't escape, then turn the valve on. The air in the hose will act as a cushion and, if water hammer is the problem, you won't hear it while the hose is connected. That is not a permanent solution, just a simple test that might give you an answer. Good luck
Q:Car water pump question!!!!!! HELP!!!!?
Well like someone else has mentioned the squealing usually comes from the round pulley that the belt rides on maybe in your case some metal has damaged the idler puller on your water pump and that would definitely give you a consent squeal. the price to replace your water pump is very excessive the part at any over the counter parts store ranges from 30-45 dollars the labor too do this on a jeep is 2.2 hrs @ the shops hourly rate which also varies but 45-55 hour isn't unreasonable... so on the high side of these figures it should be about 120.00labor 45.00 parts so a bill of $165.00 would be more appropriate......but if you don't make the repairs knowing it still has a problem you might void any type of repair warranty on your current repairs already completed...hopefully this has helped you somewhat...jimboz
Q:Three phase water pump rated power 4000W, is three-phase working water pump, the voltage is 380V, how to find the three-phase pump current, and calculation of public
Three phase water pump motor rated power 4000W is the output shaft power, divided by the motor efficiency (general 85%) is the input power, which is often mistaken. The electric power is =4000/0.85=4706WRated current = electric power /1.732x, rated voltage x, power factor =4706/1.732x380x0.8=8.94A (assuming power factor 0.8).The above three answers are all wrong.
