Product Overview
Residential and commercial dewatering applications require compact, corrosion-resistant pumps that maintain performance with minimal maintenance. The Zenit DRSTEEL37MA is a 0.37 kW submersible drainage pump constructed entirely from AISI 304 stainless steel, suitable for stormwater dewatering, pond drainage, pit evacuation, and rainwater collection systems. The unit features an internal recycle pumped liquid system that provides motor cooling even when partially submerged, and includes a standard float switch for automatic level control.
Maximum head for this model is 13.6 metres with a corresponding maximum flow of 150 L/Min, powered by a 240V single-phase motor drawing 3.1 Amps. The 0.37 kW motor operates at 2730 rpm and achieves a hydraulic efficiency of 55.6%. These specifications suit low-flow dewatering applications where portability and corrosion resistance are primary requirements.
Hydraulic design incorporates a multi-channel open impeller with a free passage of 10 mm for small solids, with the impeller manufactured from AISI 304 stainless steel. The open channel configuration maintains flow efficiency while handling minor debris common in stormwater and rainwater applications. The hydraulic system is constructed from AISI 304 stainless steel throughout, providing consistent corrosion resistance.
Construction features an AISI 304 stainless steel casing and impeller with a chrome-nickel steel lifting handle. The sealing arrangement consists of three mechanical seals with a food-grade oil lubricated oil sump, including one silicon carbide seal and one alumina graphite seal. Motor protection includes Class F insulation and IP68 ingress rating, with thermal protection and a starting capacitor included. Cable length is 5 metres with Shuko plug, and the unit weighs 6.3 kg.

How is motor cooling maintained during partial submersion?
Partially submerged operation is supported by internal liquid recirculation in DRSTEEL37MA, which keeps the motor cooled during drainage and evacuation from collection pits.
How is the pump body constructed for wet service?
The main hydraulic components of DRSTEEL37MA use AISI 304 stainless steel, including the casing and impeller for drainage service in submerged installations.
Which seal design is used for submerged service?
Three mechanical seals with food-grade oil lubrication on DRSTEEL37MA help limit liquid ingress to the motor during pumping, with Class F insulation and IP68 protection.
How does the impeller handle solids in wastewater?
A multi-channel open impeller with 10 mm passage on DRSTEEL37MA handles small solids during drainage from collection pits and partially submerged installations.
How much water can the pump move at maximum flow?
Maximum flow is 150 L/Min and maximum head is 13.6 m for DRSTEEL37MA single-phase.
