Key Features of the Hydromatic SHEF40 Effluent Pump

The oil-filled motor provides superior cooling and permanent bearing lubrication to extend the service life of your hydromatic effluent pump.

An energy-efficient 4/10 HP motor runs cool and features an automatic reset thermal overload for optimal protection.

The heavy-duty cast iron construction assists in heat dissipation and ensures durability for residential wastewater pump applications.

The semi-open thermoplastic impeller passes 3/4" spherical solids and resists impact from solid materials.

A 20-ft wide-angle piggyback float switch allows for simple conversion to manual operation and simplifies periodic cycling.

A carbon/ceramic mechanical shaft seal gives this submersible effluent pump a long, leakproof operational life.

Corrosion-resistant 2-inch thermoplastic legs raise the pump inlet off the bottom of the septic tank or sump basin.

FAQs

What size solids can this effluent pump for a septic tank handle?

The Hydromatic SHEF40A1 handles up to 3/4" (19mm) spherical solids simultaneously through its non-clog impeller and baseplate.

How do I switch the effluent pump with a float switch to manual operation?

You can easily convert the pump to manual operation by removing the piggyback plug float switch from your wall outlet and inserting the pump’s motor plug directly into the electrical outlet.

What is the maximum liquid temperature for this pump?

This pump safely handles maximum liquid temperatures up to 140°F.

Does the motor have thermal protection?

Yes, the motor windings contain a built-in thermal overload that resets automatically if the pump overheats.

What is the discharge size on the Hydromatic SHEF40A1 20-01?

This model features a 1-1/2" Female NPT discharge.

Is the power cord replaceable?

Yes, the 20-ft water-resistant SJTW power cord features a unique four-point cable entry that protects against leakage and remains easily field serviceable.

Does the pump require a strainer?

No, it features a unique corrosion-resistant non-clog base with a strainer-free inlet capable of passing solids without getting clogged.

How does the oil-filled motor benefit the wastewater effluent pump?

The oil-filled motor continuously lubricates the shaft bearings, minimizing friction and maintenance, while evenly dissipating heat for cooler, quieter operation.
