Myers® S40HT Series Submersible Sump Pumps

Capacity : 52 gpm (197 lpm)
Head : 23 ft (7.0 m)

High Temperature 4/10 HP

The Myers S40HT Submersible High Temperature 4/10 hp Sump Pump is designed for hot water applications up to 195ºF. The S40HT series is all cast iron construction with stainless steel fasteners. High temperature pumping applications include boiler blowdown pits, condensate pits and hot water transfer. The S40HT offers a cast iron vortex impeller which can pass a full 3/4" spherical solid. The S40HT is available in an automatic model with a piggyback mechanical float switch or a manual model for use with external controls.

Advantages By Design
Durable motor will deliver many years of reliable service.
  • Oil-filled motor for maximum heat dissipation and continuous bearing lubrication.
  • Overload protected, shaded pole motor eliminates starting switches and relays which are prone to fail.
  • Heavy cast iron motor housing and volute case dissipate heat, allow motor to run cooler for extended life.
The S40HT is engineered for many years of maintenance-free operation.
  • Wide angle, mercury-free, high temperature mechanical float switch for maximum draw down. (Automatic piggyback models only).
  • Automatic pump model can be operated manually by unplugging piggyback switch and plugging pump directly into outlet.
  • Cast iron vortex impeller passes a full 3/4" solid.
