Why is the self priming pump unable to fill water? 1. Reasons for the inability of the self suction pump to fill waterIf a self priming pump experiences insufficient water supply during use, it is likely due to the following reasons:1. Damaged shaft seal: The ...

The daily maintenance and maintenance of the self priming sewage pump is crucial, and the following are the relevant guidelines: Preparation before maintenance: Before maintenance, first disconnect the power supply to ensure the safety of the equipment. Instal...

In early May, a Shanghai import and export trading company purchased a large flow diesel engine self suction sewage pump from our company. The pump head of the SP-8 non clogging self suction sewage pump was selected, equipped with an 84KW diesel engine and a f...

NPSH is an important parameter that measures the ability of a pump or other fluid machinery to prevent liquid vaporization under specific conditions. It represents the excess energy per unit weight of liquid at the pump inlet that exceeds the vaporization pres...

Vacuum assisted selfpriming pump is a mechanical device that can absorb liquids and directly discharge them. Its working principle mainly uses the rotation of the impeller to generate centrifugal force, causing the liquid to form negative pressure inside the p...

Choosing a higher head for the self priming pump not only consumes excessive energy, but may also affect the lifespan of the self priming pump. To address this situation, first provide a solution based on the working principle of the pump:1. Centrifugal self p...

In the fields of municipal emergency rescue, drought and flood resistance, and more and more, not only is pump safety and convenient operation required, but the demand for pump flow is also increasing. Our company's research and development and production of l...

The SP trash pump is also called non-clogging self-priming sewage pump is with advantages of short self-priming time, self-priming, high height, strong anti-blocking ability, fast cleaning speed and so on.SP Non-clogging Self Priming Sewage Pump structure1INLE...

Today, let's take a look at the advantages of self priming pumps compared to submerged pumps?1. The overall structure of the pump is vertical, which greatly reduces weight and occupies less space compared to submerged pumps with the same parameters. Due to the...

The types of self priming pump couplings include the following:Gear coupling: This is a common type of self priming pump coupling, consisting of two different gears that can transmit a large amount of torque. Its characteristics are smooth transmission and hig...
