Features & Benefits

High pressure pumps - eliminates the need for a series of pumps, when pumping over long distances or with high head requirements
The large continuous cavities of pumps allow suspended solids to be handled with ease. The gentle pumping action also ensures delicate solids that have to be kept intact are not damaged
Can be installed vertically or horizontally
Low running speeds - ideal for abrasive applications
The rolling action of the metal rotor within the resilient stator means any solids that become trapped are released quickly, reducing abrasive wear
A range of different stator and rotor materials are available to suit individual applications, to maximize component life
The rotary positive displacement action of the pump ensures a continuous non-pulsing flow. As the discharge capacity of the pump is constant for a given speed of rotation and pressure, accurate dosing or metering of the product can be achieved

Q:A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: Modify the part: (the design of regional common fire pump should be in accordance with the requirements of the original design, building design) contains a 55m high building, and the basement is about 6m, the pump reached in the basement height about 61m (common fire pump should be based on the highest floor of other low floor area, low ring and take in this case, relief measures) 61 levels, the most unfavorable hydrant to reach 0.07MPa (maximum allowable 0.5MPa) plus loss of lift at least about 90m more appropriate, of course can be higher to take relief measures (120 too high), the basic flow of lossless (with the same time there is only one building fire) according to the maximum amount of a building fire water pump set can be, there must be a backup with a preparation, and then select the appropriate pump manufacturer specification query.(the 20 houses on 99m are only shared with a 135m pump)

Q:Pump operator's responsibility 10Sharing the rules, responsibilities, etc..: 1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.

Q:How many concrete pump tube diameter: Different pipe diameter is different, most of the 125, there are 150. Now we have the smallest pump on the market, with a pipe diameter of 100.

Q:What should I pay attention to when buying a pump?: Two, the first choice of large and medium-sized professional manufacturers, and through the quality identification of relevant departments, the market credibility of the better models, but also to the professional quality inspection institutions consultation.Three, check the motor grounding device for electric pump, water pump and motor axis, the motor should be in a proper position is provided with a grounding screw, and the grounding screw are arranged near the ground; grounding device of small submersible pump should be reliable and grounding wire, grounding wire cables should have the obvious grounding mark the flag should be in use; the motor is not easy to be worn during the period. This is one of the important safety indexes of electric pumps.

Q:Operating procedures for measuring pumps: start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not

Q:Know flow and lift how to calculate the pump power?: The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.

Q:How much water does the water ring vacuum pump run for an hour? If there is no steam separator, does the water vaporize?: For example: water storage is relatively small, it needs to reduce the temperature of the heat exchanger. If the tank is relatively large, it does not need cooling water circulation pump again when the temperature is very low, there is no need to heat exchanger. So you need to ask how much water this is not OK.In a soda separator problem:

Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same, how to choose the control cabinet?: 1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on

Q:Water pump does not produce water, what are the reasons?: 4. as a water inlet valve, check whether it is normal, whether the silted up.5. the installation height of water pump exceeds the allowable suction height of pump, or the suction pipe is too long.

Q:Why can the centrifugal pump hold down the pressure?: The centrifugal pump can hold pressure because of the suction pipe in the pump at the entrance of a non-return valve (valve).
