Effluent turbine pumps from Clarus Environmental Products are available in 11 to 85 gpm capacities with heads up to 500 feet. The 26 models of pumps range from 1/2 to 3 hp and feature 1 1/4-inch (11, 19 and 27 gpm) and 2-inch discharges (35, 55 and 85 gpm). Starting boxes are not required for pumps 1 1/2 hp and smaller but are included with 2 and 3 hp models.

All pumps have a mid-section intake, impellers that can pass up to 3/32-inch solids and corrosion-resistant, stainless steel Franklin Electric submersible motors.

Applications include STEP systems, treatment systems, dripfield dosing and sewer force mains.

“The multistage aspect of effluent turbine pumps allows them to produce really high heads,” says Darren Meyers, inside sales manager and applications engineer for Clarus.

“The other thing that’s important to note about effluent turbine pumps is they’re designed for pretty clean water. They don’t handle solids particularly well. There are a lot of ports and passageways. It’s important whenever you’re using the pumps to make sure you screen and filter effectively.”

Meyers recommends turbine pumps for use with filtered STEP vaults or pump tanks receiving filtered effluent from a septic tank filter.

“The primary reason I would think about using an effluent turbine pump would be for effluent force mains,” he says.

 “If you have a project where you’re trying to move water from a lot of residences to a common area, maybe for additional treatment, a pressure effluent sewer is a ready-made application. Another common use is dripfields because the flow into a dripfield needs to be small. Typically you don’t have flows greater than 100 gpm, even on your largest dripfields. But what you need is high pressure.”

Meyers says the sealed-end turbine pumps require little maintenance.

“We request that they be inspected just like a lot of other pumps,” he says. “Anytime you see material gathering around the intake screen you need to determine why that’s happening. Why is material getting through the effluent filters? Prevention is really the key.”
Meyers says each Clarus pump includes a history of performance and a wide range of support. “We like to think of ourselves as more than a manufacturer,” he says. “For anybody who has questions, we also offer design assistance.” 800/928-7867; www.clarusenvironmental.com.
