HOMA A Series
Non-clog submersible and dry-pit pumps, 3-500 hp, for municipal and industrial wastewater.

Non-clog, grinder, effluent and stainless steel submersible pumps from HOMA Pump Technology.
HOMA Pump Technology (Ansonia, Connecticut) makes submersible wastewater pumps for municipal, industrial, commercial and residential use. Its US range is organised into series: A, GRP, TP, C, OC and HRS. Here we cover the four series most often specified for wastewater and sewage.
HOMA pump series
HOMA GRP Series
Grinder pumps, 1-15 hp, with a hardened external cutter.
View →HOMA TP Series
Effluent pumps, 1-5 hp, for commercial, industrial and light municipal duty.
View →HOMA C Series (CA & CTP)
Stainless steel (316 or duplex) non-clog and effluent pumps for aggressive liquids.
View →Features shared across the range
- Class H motor insulation on A, GRP and TP Series motors.
- Temperature and leakage sensors fitted as standard on A and GRP Series pumps.
- Explosion-proof options: FM approved variants for Class 1, Div. 1, Groups C & D locations.
- Stainless steel option: CA and CTP pumps keep the hydraulic curves of their cast iron A and TP counterparts.
Choosing between non-clog, grinder and effluent pumps
Non-clog (A Series) pumps pass solids through large impeller passages and suit lift stations with higher flows. Grinder pumps (GRP) cut solids so sewage can travel through small-diameter pressure pipe over long distances or high lifts. Effluent pumps (TP) handle liquids with fewer solids, such as drainage water or treated effluent.
Sizing considerations
- Flow (GPM): estimate peak inflow to the basin or wet well. For effluent dosing, use the dose volume and dosing time set by the system design.
- Total dynamic head (TDH): add the static lift (vertical rise from pump-off level to the discharge point) to friction losses in the pipe, fittings and valves. Choose a pump whose curve crosses your system curve near its best-efficiency range.
- Solids: clear water, effluent, raw sewage or fibrous waste each need a different impeller or cutter. Match the pump's solids-handling rating to the liquid.
- Power supply: confirm voltage and phase (115/230 V single-phase or 208/230/460 V three-phase) and whether start components sit in the pump or the control panel.
- Basin and controls: basin size, pump-down volume, float or level-sensor setup, and a high-water alarm.
- Environment: corrosive or abrasive liquids may call for stainless steel. Classified (hazardous) locations need explosion-proof, approved motors where the code requires them.
- Codes and permits: onsite septic and lift station work is regulated locally. Follow the approved design and local requirements.
Frequently asked questions
Which HOMA series do I need?
Use the A Series for large municipal and industrial solids handling, the GRP for grinding into pressure lines, the TP for effluent and drainage, and the stainless C Series (CA and CTP) for corrosive or abrasive liquids.
Are HOMA pumps available for hazardous locations?
HOMA offers FM approved explosion-proof variants for Class 1, Div. 1, Groups C & D hazardous locations across the A, GRP, TP and C Series. Availability varies by model.
Can HOMA grinder pumps retrofit an existing sump?
HOMA offers a wide range of competitor adapters for GRP Series grinders, so they can be installed in existing sumps.
