Strong Self-priming Pump

The strong self-priming pump is a newly developed self-priming sewage pump model. The pump body is made of stainless steel, and all the over-flow gold components are stainless steel (1Cr18Ni9Ti). The impeller is made of butadiene rubber or EPDM rubber soft material, which not only has good elasticity and small deformation, but also can withstand long-term high frequency flexion without breaking and tearing, so it will not cause damage when conveying hard solid particles such as nuts. Ding Qing impeller is mainly used in vegetable oil, mineral oil, oil-containing media and areas with high health requirements; Ethylene propylene wheel is mainly used in weak inorganic acid, organic acid, alkali, salt, alcohol, ketone, sewage and other wide range of media. It has the advantages of large flow and small size. Compared with competitive pumps, it has small volume under the same flow and is easy to install and move. And the self-priming ability is strong, there is no need to replenish liquid before starting, and instant self-priming can be achieved without any additional device.

The self-priming performance of the strong self-priming pump and the strong working condition adaptability make it used in a variety of industrial occasions, the suction and drainage of the liquid in the underground tank, the sampling and the transportation of various fluids and semi-fluids, such as the import hose only needs to be inserted into the barrel when the bucket is poured. Widely replaced centrifugal self-priming pump, hydraulic pump, gear pump, single screw pump and other pumps.

The strong self-priming pump has small volume and small noise, so it occupies small installation space for on-site equipment and makes little noise in the installation room. And the structure is simple, convenient maintenance, do not need professional guidance, maintenance does not need to remove the pump pipe, the purchase of the pump lifetime use, less wearing parts. The viscosity of the conveying medium can reach 5000 cm, and hard particles containing particle impurities can be transported. It is characterized by strong self-suction, because of the structural principle, dry self-priming up to 6 meters, with material self-priming up to 9 meters, and the self-priming time is short, instant self-priming within 6 meters (2-3 seconds to complete). Large flow high efficiency, small power saving under the same flow.

There is an eccentric convex block in the pump cavity, and when the flexible blade leaves the eccentric block, the volume between the blades continues to increase, resulting in a vacuum, which makes the liquid continuously sucked into the pump cavity inlet. When the flexible blade rotates, the liquid is brought into the discharge part by the suction part of the pump chamber. When the flexible blade contacts the eccentric convex block again, it bends, and is accompanied by an extrusion action, making the liquid discharge the pump chamber uninterrupted and without pulsation, thus completing the whole process of suction and discharge.

The viscosity of the conveying medium can reach 5000 cm.

It can transport gas-containing liquid and foam liquid without gas resistance.

It can transport medium containing suspended soft and hard particles.

The gentle action of the rotor does not damage the shear sensitive media, such as paper dispersants.

When the flexible rotor is running, there is no metal contact and no spark. With explosion-proof motor especially suitable for alcohol, gasoline, acetone and other solvents transport.
