Goulds Submersible Well Pumps are used to draw water from a well in an area where there is no connection to a municipal water line. In this blog, we will highlight Goulds Submersible Well Pumps

Typically found in rural or outlying areas, well pumps can be used for a variety of applications, including farming, irrigation or simply drawing potable water.

Two broad categories of well pumps exist: submersible and jet pumps. As the name suggests, the submersible well pumps are submerged under water at the bottom of the well. Jet pumps are installed above the well and require a separate jet assembly component (twin pipe, Packer) actually installed in the well.

Goulds Pumps are compact, close coupled single-component and can be configured for deep well applications.

Performance

The model highlighted here is a low-flow, high head model that can perform in deep well applications. The best efficiency flow rate for the 5GS10412C is 5 gallons per minute, while the head can reach over 600 feet TDH.

The pump accomplishes the high heads through the use of multiple stages. A “stage” is simply a compartment consisting of a diffuser, upthrust washer, impeller and a bowl. The model highlighted here includes 20 stages stacked on top of each other.

The mechanism is straightforward: water enters the inlet and moves up through the stages. The rotating impeller reacts against the stationary diffuser vane, increasing water pressure. As the water moves through each successive stage, the actions is repeated and pressure continues to increase exponentially.

A key point to remember is that the number of stages is positively correlated with head and inversely correlated with flow; the fewer stages, the higher (in terms of GPM) the best efficiency flow rate. We carry Goulds Submersible Well Pumps with various stages in our store.

It is a Floating Impeller Stack (as opposed to a fixed impeller stack) which has proven itself for over 50 years as a superior sand handling and durable pump design. It is also more flexible than a fixed impeller stack.

This package includes a compact Centripro control box for simple start-stop management.

Construction

As with any Goulds Submersible Pump, durability is an important consideration. Rust and corrosion are dangerous impediments to any type of equipment that operates submerged under water. If you are relying on such a pump for your potable water, you need to be especially attentive to the possibility of damage.

Goulds Well Pumps feature some of the most rugged top-to-bottom construction of any submersible well pump on the market.

It starts with the outer casing, which is made of durable, corrosion-resistant stainless steel. The check valve is stainless steel as well, while the discharge head is cast stainless steel. Noryl impellers and Lexan diffusers also ensure that the pump internals are resistant to abrasion. The engineering polymer bearing ensures durability throughout the pump body.

4” Centripro motors are both powerful and durable for continued best performance operation. Pumps with motor packages are available as are pump ends or “wet ends” only. Packages that include control boxes are available as well.   

Be sure to consult your local well specialist for installation and maintenance purposes.
