Product Details

The Model 137 family of effluent and dewatering pumps is engineered to deliver rugged, dependable performance in sump and septic system applications where reliability is critical. Powered by a 1/2 HP split‑phase motor, each Model 137 pump features an oil‑filled motor chamber and finned cast‑iron motor housing to ensure optimal heat dissipation, allowing the pump to operate efficiently during extended or continuous‑duty cycles. Designed to handle the demands of residential and light commercial basement and septic systems, these pumps combine Zoeller’s proven hydraulic design with durable construction for long service life.

A cast‑iron vortex impeller enables the handling of 5/8‑inch spherical solids, reducing clogging and minimizing maintenance while maintaining strong, uninterrupted flow. With performance capabilities up to 26 feet of head and 90 GPM, the Model 137 excels in applications requiring higher flow and moderate head, including effluent pumping, septic tank dosing, and general dewatering. The powder‑coated epoxy finish protects against corrosion in harsh environments, and stainless steel screws, handle, and hardware enhance overall durability.

Available in multiple cord lengths to match your application needs, the Model 137 family is backed by a 3‑year warranty, reflecting Zoeller’s commitment to performance quality and long‑term reliability. When you need a pump built to withstand the challenges of septic applications while delivering smooth, consistent operation, the Model 137 family is a trusted choice — Trusted. Tested. Tough.®

Features and Benefits
  • Oil-filled motor and cast iron motor housing for optimal heat dissipation which prevents the pump from overheating
  • Snap-action models provide preset automatic operation for basement sumps. Piggyback models offer a wider, adjustable operating range for use in both basement sump and effluent applications, while nonautomatic models require an external float switch or control panel for effluent systems
  • Cast‑iron vortex impeller capable of passing 5/8" spherical solids, minimizing clogging and reducing downtime.
  • Stainless steel float guard (applicable for automatic pumps) that prevents material or debris from collecting on the float ensuring proper operation every time
  • Solid, buoyant, polypropylene float (applicable for automatic pumps) to eliminate the possibility of water infiltration allowing the float to remain buoyant and functional at all times
  • Powder-coated epoxy finish provides corrosion-resistance and extends the life of the pump in harsh environments
  • Stainless steel screws, switch arm, guard, handle and hardware to prevent rust and corrosion over the life of the pump
  • 100% Factory Tested - every pump is submerged in water and tested at the factory to ensure that it performs as expected when you receive it
  • Comes with a 3-year limited warranty giving you protection over your investment and the peace of mind you expect in a quality product
