1. Production Introduction
WZB self-priming pump is divided into single phase and three-phase asynchronous types with built-in protection device. The pump is divided into centrifugal impeller and worm casing structures with self-priming function. Single-face mechanic sealing is mounted between pump and motor."0" shaped oil-proof rubber seating ring is used at each stationary port as static sealing.

2. Application
This series pump is a new type of ideal economical pump, widely used in pumping water, 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 operational 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°C and PH should be 6.5-8.5.
3.Power frequency should be 50Hz,single phase voltage 220V, three-phase voltage 380V,and voltage fluctuation should be 0.9-1.1 times than the rated.

4. FAQ

1. With regarding the submersible pumps, we can just get a pump head?

It would be acceptable to arrange the pump head alone. All connections are conforming with the international standard. But it is also very necessary to have a confirmation before the delivery, because there are some models which is special.

2. Do you have smaller solar pump?

Yes, we have. Except the solar submersible pump, we also have some surface solar pump, the voltage about it is 12V or 24V. The materials about them are plastic.

3. Can you customize the pump when we needed?

 This is acceptable. But we have to charge some fees in advance, because we need to make the new moulds for it sometimes.

Q: How to adjust the flow of piston pump?
Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.
Q: What is a water pump coupling device?
The water pump coupling device comprises a coupler, a coupling flange, a guide rod and an upper fixing plate, wherein the contact surface of the coupling base and the coupling slide plate is provided with an annular groove, and a soft sealing gasket is tightly fixed on the groove. By adopting the structure, the coupling contact surface of the coupling slide plate and the coupling base is sealed firmly by an annular sealing groove
Q: What is the difference between swashplate pump and crankshaft pump?
Swash plate pump motor is driven as a coaxial swash plate drive plunger pump crankshaft work produces high pressure water in general simply and motor rotor to form a 90 degree angle of the motor through the crankcase to drive the piston to work in general the crankshaft speed is relatively high in the 2800 turn left and right to use the cost of the swash plate speed the use of less than 300 kg pressure in about 1400 when the crankshaft is relatively high but in more than more than 300 kilograms of crankshaft pump highlights his advantage.
Q: What does "anti pump" mean in pump operation?
The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)
Q: The distance from the pump button to the ground
After confirming that the fire pump has started running, issue a command signal to the hydrant button to light the green answer light.
Q: What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
Q: What is the pump delivery? What's the difference between years and years?
1) integer integer: ~ batch. Sell ~.2) buy in bulk: ~ goods. Sell now.The exchange is, according to the duration of the contract delivery insurance premium, payment is generally in common, 5 years of insurance you every year that time, continuous call five years; general single sex 5 years or even 10 years of premium.Furthermore, the insurance premium is good or good pay period, if a single rate from the point of view, to make cheaper than single period, but considering the one-time payment of the interest cost of funds and the opportunity cost, there is no difference. While the single cross ratio advantage is mainly reflected in its flexibility. First of all, additional premium may be added to the premium. At present, additional risks can only be covered if the main risks and principal risks are covered during the payment period. The single way to buy insurance, even in the primary insurance protection period will no longer be able to purchase additional insurance new; secondly, to pay the premium can enjoy a premium waiver. If the insured in full payment period has not yet had the danger, not pay part of the premium would be exempt from the Qing dynasty. For child insurance, the premium waiver is more advantageous. If parents unfortunate accidents or illness, resulting in death or one or two, three disabled or suffering from severe illness, the insurance company will be exempted after the premium, the insurance contract shall continue to be valid; finally, to pay the premium or additional premium amount can be changed. The policy holder may adjust his insurance plan according to the change in his economic strength. In contrast, single premium has the advantage of a one-time payment more convenient.
Q: Is vane pump good or gear pump good?
1) the reversible design of gear pumps can also usually reverse, but reverse after the suction port change, and the pump safety valve does not work; leaf pump is generally not allowed to reverse. 3) the single acting vane pump can be designed to change the eccentric distance by moving the stator at the constant speed, so as to achieve the purpose of variable direction.
Q: What is the difference between the ground pump and the pump in the commercial concrete?
Day pump: the pump and pipe will be placed in a position on the site, the pipe in the air like the crane arm
Q: What do you mean by the self coupling device on the pump?
Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.
