High-efficiency effluent pump

The 1/2 hp CPSTEP512 pump from Champion Pump Company pumps up to 85 total dynamic head (TDH). The 1/2-inch solids handling pump comes in a single or double seal design. The double seal design is available with a seal failure option notifying the operator that the first seal has failed.

The high-efficiency permanent split capacitor (PSC) motor with upper and lower ball bearings is designed for long life and is available in 115V or 230V. A three-phase 230V or 460V unit is available. The pump is also available with up to 2 hp with shut-off heads and capable of 123 TDH. The 20-foot power cord (up to 50-foot lengths available) has a sealed entry, allowing the plug to be cut off when connecting to a junction box or control panel without voiding the warranty. The sealed entry prevents water from entering the motor housing through the cut power cord. 800/659-4491; www.championpump.com.

 

Linear air pumps

Envir-o Linear air pumps from Charles Austen Pumps for aerobic treatment units combine a specially formulated diaphragm material for extended life with energy-efficient motors for low power consumption. Only a screwdriver is needed for servicing. A compact alloy casing is weatherproof and does not degrade over time.

An electromagnetically operated diaphragm eliminates sliding parts to reduce wear and tear. Combined with a noise-absorbing double damping system within the casing, the pump emits 40 dBA. A range of models is available with flow rates from 8 to 50 gpm. 770/831-1122; www.charlesausten.com.

 

Turbine effluent pumps

Turbine effluent pumps from Clarus Environmental include six core families grouped by nominal flow rate. Within each family, pumps are arranged by the number of stages and motors sizes, from 1/2 to 3 hp. There are 26 models with a flow range of 11 to 85 gpm.

All pumps feature a mid-section intake, corrosion-resistant stainless steel motor and pump casings, and jacketed cord available in 10-, 25-, 50- and 100-foot lengths. Applications include septic tank effluent pumping (STEP) systems, effluent sewer force mains, soil absorption systems and dripfield dosing. The pumps can pass up to 1/8-inch spherical solids. Pumps come with all necessary starting components. 877/244-9340; www.clarusenvironmental.com.

 

High-performance pumps

Little Giant 6EN and 10EN sump and effluent pumps from Franklin Electric feature permanent split capacitor (PSC) motors, providing low current draw, energy efficiency and improved performance. Designed for extended or continuous use, the pumps are fully submersible and made for dewatering and light effluent applications. The 6EN creates pump stability and lower intake velocities, while providing high-performance capabilities. The 10EN is built for more difficult applications. 405/228-1204; www.franklin-electric.com/lg.

 

Backup system

The ReliaPrime emergency bypass station from Gorman-Rupp Co. operates on natural gas, making it quiet and environmentally friendly. The unit features a 6-inch Super T Series pump capable of passing 3-inch spherical solids and offers a soundproof, lightweight aluminum enclosure. The enclosure has padlocked door panels and can be removed for maintenance. The unit is a complete backup package, ready for hookup. 419/755-1011; www.grpumps.com.

 

Leakproof pumps

S pumps from Grundfos include the SmartTrim impeller clearance adjustment system and the SmartSeal for leakage prevention. SmartTrim allows the operator to adjust the factory-set impeller clearance to maintain maximum pump efficiency. The SmartSeal auto-coupling gasket provides a leakproof connection between the pump and the base unit of the auto-coupling system.

The shaft seal can rotate in either direction. When the pumps are installed with separate pipework, sludge sedimentation can be avoided by backflushing the system at regular intervals. The pumps are suitable for applications including transfer of unscreened raw sewage, transfer of raw water, pumping of water containing sludge, and pumping of industrial effluent. 800/921-7867; www.grundfos.com.

 

Full-access aerator

The wastewater aerator from Jet, Inc. provides full access to the company’s complete product support network, which includes in-house customer service, technical support staff and factory-trained on-site service technicians. The unit provides an exact amount of mixing and air to the biologically accelerated treatment (BAT) media plant, producing a clear odorless discharge. 800/321-6960; www.jetincorp.com.

 

Grinder pump

The Omnivore LSG-Series 2 hp grinder pump from Liberty Pumps features V-Slice Cutter Technology, providing 372,000 cuts per minute for superior shredding performance in demanding applications. The pump’s open-volute design eliminates the cutwater, improving solids flow and reducing potential jamming. Other features include one-piece cast-iron body, quick-disconnect power cord, stainless steel impeller and dual-shaft seals. Complete preassembled systems are available. 800/543-2550; www.libertypumps.com.

 

Air pumps

ET Series air pumps from Polylok provide a clean, oil-free air source and are vibration-free. Suitable for continuous duty, they operate as low as 30 dB with the vacuum assisted noise-reduction system. The pumps are housed in a portable weatherproof compact casing, offering simple plug-and-run operation. They require little to no maintenance or service. Applications include sewage aeration and aquatic oxygenation. Several models are available in steps from 11 to 40 gpm. 877/765-9565; www.polylok.com.

 

Pump variety

The Plus line of high-head turbine pumps from Quanics are available in 10, 20 and 30 gpm models with head capacities up to 250 feet. The 1/2 hp 115-volt motors have minimum 24-hour run dry capability and offer thermal overload protection. The pumps are constructed of 300-grade stainless steel and engineered composite materials. The bottom intake design allows for greater drawdown and eliminates flow inducer sleeves. 877/782-6427; www.quanics.net.

 

Compact air pump

The Whirlwind STA linear air pump from Septic Services can be used as a replacement for all 60, 80 and 100 model pumps. The light and compact pump operates quietly and features an inside threaded outlet pipe and 6-foot power cord. The STA-60 and STA-80 models are also available with a hose bib for low-pressure alarm. The STA-80 comes standard with oversized, thick diaphragms and large shuttle for longer life and durability. Easy to install and maintain, the pump does not require lubrication or any tools to replace the included filter. 800/536-5564; www.septicserv.com.
