Pumping Performance

The latest innovations in pumps and blowers give onsite installers more options when designing treatment systems

Growth in advanced onsite wastewater treatment systems by definition means growth in sump, sewage and aeration pumps. Here are several new offerings from manufacturers of those products.

High-head Turbine Pump

The 5030-0007 turbine pump from Zoeller Pump Co. filters effluent pumping in high-head applications. Its 115 V (or optional 230 V) motor runs cool while driving a stainless steel shaft. Seven stages of impellers enable the pump to achieve 241 feet of total dynamic head. Flow from the 1 1/4-inch glass-filled Noryl discharge is 11 gpm at best efficiency where it overcomes more than 120 feet of head. The pump is used in mound, drip or media filter systems, and STEP collection for decentralized and pressure sewer applications. 800/928-7867; www.zoeller.com.

Pump-tank Package

Installers no longer have to piece components together or make field cuts with the EasyPak pump package from Orenco Systems Inc. The box contains everything needed to pump effluent from dosing tanks. The 4-inch turbine effluent pump in a low-profile filtered vault pumps nearly to the bottom of the tank and lasts millions of cycles. Packages for timed or demand dosing also include the float and discharge assemblies, splice box and control panel. 800/348-9843; www.orenco.com.

Larger Horsepower

The FL-series of effluent pumps from Liberty Pumps now includes single and 3-phase 1-, 1.5- and 2-hp models with flows to 130 gpm and maximum heads to 130 feet. They have 1 1/2- and 2-inch discharges for connecting to either size pipe. 800/543-2550; www.libertypumps.com.

Aeration and Mixing

The Jet Aerator system from ITT Water and Wastewater Corp. provides mixing and simultaneous aeration in sequencing batch reactors, sludge storage basins, and decentralized wastewater treatment plants with flows of less than 1 mgd. The system has a Flygt submersible N-pump, an air suction tube, and an ejector/diffuser assembly, all suitable for any tank size, shape or depth.

Different ejectors enable the system to perform oxygenation, aerobic sludge digestion, ozone treatment, mixing, foam suppression and homogenization (mixing). Units are self-aspirating to depths of 21 feet, but will work with blowers, if needed. Installation requires no major modifications to existing structures. 203/380-4800; www.flygtus.com.

Pump Stations

Lightweight yet durable pump stations from Premier Tech Environment arrive preassembled and ready to plug in. The PSA-240 lifts wastewater to biofilters or other septic installations. The PSA-240L pumps treats effluent from STB-500/650 Ecoflo biofilters with submersible collecting bottoms. Model PSA-240H pumps to low-pressure distribution drainfields. Internal components are easy to access and secure from unauthorized entry. 800/632-6356; www.ptenv.com.

Detects Oil

Three Oil Detective sump systems from Blue Angel Pumps alert the presence of oil in various applications. Systems for 1/3 hp (65 gpm at 5 feet) up to high head 1/2 hp (50 gpm at 20 feet) include cast-iron or cast-iron/stainless steel pump, pump controller, audible alarms, visual display lights, preset on/off, 20-foot piggyback switch cord, UL508-approved switch, and instructions. 888/636-6628; www.blueangelpumps.com.

High-efficiency Effluent Pump

CPSTEP512 1/2-hp effluent pumps from Champion Pump Co. Inc. pass 3/4-inch solids, achieve 93 feet of total dynamic head, and have single or double seals. The high-efficiency permanent split capacitor motor has upper and lower ball bearings. Power cords up to 50 feet long have an outer jacket seal, allowing plugs to be cut off when connecting to junction boxes or control panels without voiding the warranty. A sealed entry prevents water from entering the motor housing. 800/659-4491; www.championpump.com.

Vertical Discharge

Stainless steel submersible Unilift KP pump models from ­Grundfos Pumps Corp. have a vertical discharge port and integrated single-phase canned motor in insulation Class F with thermal overload protection. Even partly submerged, these light, compact units transfer clean or slightly dirty wastewater with 3/8-inch solids and fit­ into narrow drainage pits. The pump, fitted with suction strainer and carrying handle, has a float switch for automatic start and stops, and a 16-foot cord. Single-curved vanes with beveled front edges prevent the semi-open impeller from clogging. The motor has a liquid-filled rotor chamber and water-lubricated bearings. The main cable secures to the socket of the hermetically sealed housing. 913/227-3400; www.grundfos.us.
