Product Description:

1. Production Introduction: 
JET series pumps have the advtanges and characteristic of self-priming pumps and centrifugal pumps. Water jet elements realize self-priming function.Pumps by the optimized design, have the advantages of bigger suction, high head, smooth operation, and reliable performance, which is the ideal tool for agriculture, and household, etc

2. Application:
This series pump is a new type of ideal economical household pump, and widely used in pumping water from well, increasing water pressure, garden irrigation, water supply for vegetable green houses, industrial mining enterprises and aquatic breeding fields etc.
3. Work Conditions: 
The pump can work properly and continuously under following op¬erational conditions:
1.Medium is not corrosive. Sand contents should be max.0.10% by volume and granular size should be max.0.20mm.
2.Medium temperature shouldn’t be over 40℃and PH should be6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, and voltage fluctuation should be 0.9-1.1 times than the rated.

4. FAQ

1)  Are CNBM pumps available in DIY stores?

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

2)  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.

3) 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.

Q:Harm of air pump and pump
If the liquid is not full, this situation is generally the suction pipe or pump shell leakage, then easy to cause cavitationHit the pump for centrifugal pumps, centrifugal pump is recommended to start closed, the discharge valve closed, starting is in the state of pump
Q:Working principle and diagram of axial piston pump with pressure compensation variable
Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.
Q:Is the vacuum pump air compressor?
No, both work in the opposite way. Air compressor, referred to as an air compressor, is a machine that produces compressed air (positive pressure). The vacuum pump is just the opposite.
Q:Is the flow meter in front of the pump or after the pump?
After the pump, the reasons are as follows, before the pump, you pump fluid through the pump will produce negative pressure in front of the pump, negative pressure on the flow of the life of the impact, the pump will not, Suzhou first Chi meter
Q:Why does the centrifugal pump start and close first when the outlet valve is closed?
The operation rules of centrifugal pump strictly required to close the outlet valve before the shutdown, boot and then slowly open the outlet valve, regulating pipeline pressure and current range. The reason is: the centrifugal pump in the startup process in order to avoid large starting current caused by electrical faults, such as circuit breaker tripping,
Q:What are the internal losses in centrifugal pumps? How did they come about?
Due to the friction of the bearing, the friction in the stuffing box, and the losses caused by the rotation of the impeller (the loss of the roulette wheel);
Q:What does "efficiency" mean in a water pump catalog?
Pump efficiency: the ratio of the effective power and the pump shaft power
Q:How to select hydraulic pump?
Select the hydraulic pump from the following considerations:1. hydraulic pump pressureHydraulic pump operating pressure is the pump (or motor) in actual work output (or input) oil pressure, determined by the external load.Rated pressure refers to the maximum pressure under continuous running in accordance with the test standards under normal working conditions. The size of the pump is limited by the service life, and the service life of the pump (or motor) will be shorter than the design life if it exceeds the rated pressure. When the work pressure is greater than the rated pressure, it is called overload.
Q:Why is the sewage pump device coupler?
Advantages of installation and arrangement of sewage pump coupling:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device under the condition of fixed installation, such as pump fault maintenance personnel need to unscrew the screw pump lifting water, repair, or other small pump to pump the water down perfect maintenance, if the water is dirty, it would be difficult for people to go to the next, then the overhaul had great difficulty.
Q:What are the starting and stopping procedures for centrifugal pumps?
The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
