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

 

Horizontal Direct Linking of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  • Features: It is directly driven by gear motor, compact structure, short length of the pump

  • Parameters: 600m³/h; maximum pressure: 2.4MPa or higher

 

 

FAQ

  • Are your pumps protected against dry running?

    No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

  • How can I get trained on CNBM products?

    Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

  • Are your pumps cheaper than those of your competitors?

    CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q:How do you do the yellow water from the suction pump?.
The pump is iron, must be able to avoid the internal rust, and if replaced by stainless steel, no problem.There is also a way to add a filter or water purifier at the front of the pump to make it a little better.
Q:25KW what is the lift of the pump?
Give you a formula for estimating the power of a pump:N=Q (L/s), *H (m), /102/ (0.6~0.85), /0.85Explanation is:N, the power unit is kW (kW)Q, flow, in units per liter (L/s)H, the lift is m102 is 1000/g, G, that is gravity acceleration, is a unit conversion0.6~0.85, the efficiency of the pump, the general flow of large values, small flow of small value;0.85, power factorIn addition, there are some general power pump module, since there are: 1.1kW, 2.2kW, 3kW, 4kW, 5.5kW, 7.5kW, 11kW, 15kW, 18.5kW, 22kW, 30kW, 37kW, 45kW, 55kW, 75kW, 90kW, 110kW, 132kW......And generally there is no 25kW pump.
Q:Submersible pump and self-priming pump which is easy to use?
Dive into the water and leave alone
Q:How can I pump the motor insulation?
A submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the electric box so that the pump shell shake shake, also must be reliable grounding to shake to now, the pump shell grounding not only in the water, it must be a wire connected with a shell or a wire will be immersed in water, this is right insulating shake,
Q:Submersible pump reverse impact on the pump
The pressure is too small, the current is too large, the operation time is too long will burn out the pump!
Q:Think of several households sharing a pump
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:Two pumps automatically switch start control circuit,
The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
Q:What does water flow mean?
The quantity of water produced per hour
Q:Is the motor with a pump a squirrel cage induction motor?
Not necessarily, mussaurus main motor and conventional motor rotor winding is the difference of mussaurus, can be in series with other equipment, to achieve more functionality!
Q:Safety head of water pump?
Pump selection should pay attention to the following points: (1) to meet the maximum load conditions, should try to reduce the waste of energy; (2) rational use of high efficiency section of the pump; (3) using the same type pump as much as possible, the type of neat, standby each other; (4) to the selection of large pump according to the actual situation, but also should consider taking into account the size, flexible deployment; (5) lack of H value changes, different types of collocation is optional pump operation. (6) to ensure the water conditions, take care of basic level, reduce the pumping depth; (7) consider the standby unit necessary; (8) check the fire with water; (9) considering the development, implementation of the combination of short and long term; (10) to the selection of water pump type local mass production.
