HT40-Series

Product catalog summary

Overview: The HT40-Series is a high-temperature submersible pump designed for hot water applications up to 200˚ F, such as boiler blowdown pits, hot water transfer, and condensate pits. It features a 4/10 horsepower motor and a 1-1/2" discharge, capable of handling solids up to 3/4".

Models: The series includes four models: HT41M, HT41M-2, HT41A, and HT41A-2, differing in cord length (10' or 25') and operation type (manual or automatic).

Features: The pump includes a vortex impeller made of high-temperature engineered thermoplastic, cast iron construction with stainless and brass fasteners, a 416 stainless steel rotor shaft, an oil-filled, thermally protected motor, and permanently lubricated bearings. It also has a unitized shaft seal and a U.L. approved power cord with a quick disconnect design.

Technical Specifications: The pump operates at 115 volts, single phase, with a 12 amp draw. It features a class F insulation motor, hermetically sealed and thermally protected, with an automatic reset overload element. The impeller is designed to pass 3/4" spherical solids, and the shaft seal is carbon/ceramic with high-temperature elastomers.

Construction: The external construction includes heavy gray iron castings, enamel-coated before assembly, with all fasteners made of 300-series stainless steel or brass. The pump is controlled by an adjustable mercury-free switch with a manual by-pass operation option.

Performance: The pump's performance is illustrated in a graph showing gallons per minute against total head in feet, with performance varying based on water temperature (77˚ F vs. 200˚ F).

Dimensions: The HT41M model weighs 36 lbs, with a height of 9.6" and a major width of 9.8" for manual models. The maximum fluid temperature is 200 degrees F.
