HCP Pumps offers high-quality, competitively-priced self-priming suction lift pumps. Our Suction Lift series is effective, reliable, and built to last. Like all our products, these self-priming pumps are built to perform to a high standard. HCP Pumps strives to deliver top-quality equipment at a reasonable price.
What is a Self-Priming Suction Lift Pump?
In a suction lift configuration, the pump centerline sits above the liquid being pumped. Because the pump is above the liquid, suction is required to lift the liquid up and into the pump.
There are several possible options of pumps that can work with a suction lift configuration, such as vertical turbines and submersible pumps. However, vertical turbines only work well with relatively clean water, and while submersible pumps can handle solids, they can require more maintenance. A submersible pump will be covered in whatever liquid it has been submerged in, necessitating cleaning. A self-priming centrifugal pump can handle solids, and because it doesn't need to be submerged, it remains clean.
Technically, even a standard centrifugal pump that can handle solids can work in a suction lift configuration-- with a caveat. Because the pump sits above the liquid to be pumped, there will be air in the line or pipe between the pump and the liquid. A standard centrifugal pump cannot create suction with all that air, so it will have to be primed.
The benefit of a self-priming suction lift pump is that it comes equipped with a reservoir. This reservoir must be filled with an adequate amount of water before is it powered on. (This step is crucial. Attempting to run a self-priming pump with an empty reservoir will cause a mechanical seal failure and possibly further damage to the pump's internal components.) Once primed, a self-priming pump will automatically hold enough water in reserve to self-prime. This eliminates the need for repeated manual priming and makes them a ideal choice for frequent and intermittent pumping operations.
What are Self-Priming Suction Lift Pumps Used For?
Self-priming suction lift pumps are typically used to move industrial or municipal wastewater. They are frequently used in sewage lift stations, to pump raw sewage into the treatment facility. Self-priming pumps are also a common choice for removing storm water and for use in paper mills and the poultry industry. They are a popular choice for dewatering on construction and mining sites, where their ability to handle debris has lead some in the industry to refer to them as "trash pumps".
Self-Priming Pumps: Suction Lift Series
HCP Pumps' self-priming suction lift pumps are capable of priming without a flap valve. They are non-clogging and able to handle large solids. The unique lubrication of the mechanical seal cavity gives this pump more reliable performance. HCP Pumps' Suction Lift Series is equipped with a pressure relief valve, solids-handling impeller, abrasion-resistant seal, removable cover plate with easy-grip handle, replaceable wear plate, and a removable rotating assemble. This self-priming pump has low rotary speed, reliable operation, easy maintenance, and a long product life-- making it a valuable and wise investment.
