Product Description

 

product introduction

Self-priming pumps are a specific type of liquid pump designed to have the required liquid inside the cavity or pump body necessary to start the pumping process. This offers the potential for increased operating efficiencies in process plants where pumps are used for a variety of repeated yet intermittent operations.
If a pump is located beneath the level of the liquid to be pumped, gravity and air pressure ensure that it is constantly filled with the liquid and there can be no ingress of air into the pump or suction line.

In order to balance axial thrust, there are both wear rings in front and at the back of the majority of the impeller and the balance hole is on the back shroud of the impeller. The axial thrust of some pumps is not big enough, so there is no wear ring and balance hole at the back of the impeller.

High-precision casting impeller can ensure the performance, material in cast iron, stainless steel and bronze.

 

Packing pump cover is equipped with stuffing, for soft packing seal, the stuffing may pass into a certain pressure of water for seal cooling, lubrication, cleaning;
Single mechanical seal and double mechanical seal two species for mechanical seal, a certain pressure into the seal cavity through the water, rinse the end surface friction, while cooling effect. According to demand while allowing the use of a sealed cavity adapted to form a predetermined size of ISO3069 other structures, such as mechanical seal with corrugated pipe and expeller seal.

Flexible couplings
Unlike rigid couplings, flexible couplings can accommodate some movement e.g. vibrations and thermal expansion without damage. This makes them ideal for applications where there is a degree of unavoidable misalignment between the drive and pump shafts. As they can absorb vibrations well, they can also be used to reduce excessive operating noise. With these benefits come a more complex, expensive design. However, as flexible couplings protect the shaft and bearings from damage and premature wear, there are maintenance savings to be had in the long run.

We use wear-resisting disc coupling or pin coupling.
