A Better, Faster Way to Source Pumps

Multistage Pumps

What is a multistage pump?

A pump that contains different stages within the piping system where force is applied to the water. Each stage consists of one impeller as well as its accompanying diffusion components. The term “multistage” is usually used in reference to centrifugal pumps.

In many cases, these pumps are referred to in terms of how many stages they contain. For example, a pump with four stages might be referred to as a four-stage pump, or one with 10 stages would be referred to as a ten-stage pump.

How do multi-stage pumps work?

The idea behind multistage pumps is fairly simple. In many industrial and fluid treatment facilities, it’s necessary for fluids to be moved large distances with higher pressure. In many of these situations, the only way to achieve this higher pressure is with more than one impeller. The multiple impellers are mounted on the same shaft, and the flow progresses from one stage to another, building pressure as it goes.

Graco introduces a new hose pump that uses a single, oversized roller that compresses a low friction hose through a full 360-degrees of rotation. This design can put 40% less stress on the hose compared to conventional shoe pumps running at the same flow rate. The pump also has 50% more fluid flow per revolution than C-shape positive displacement pumps.
