Description
FORWATER DTM-E20B Single-Stage Centrifugal Pump
The DTM-E20B is the high-flow variant of the DTM-E20 single-stage centrifugal pump, offered in two power ratings — 1.1 kW (1.5 HP) and 1.5 kW (2 HP) — for conveying clean water and liquids similar to water. Both ratings turn at 2,850 r/min and share full-bore 3" (76 mm) ports with an 8 m maximum suction lift; the 1.1 kW rating delivers a 15 m maximum head with up to 500 L/min, and the 1.5 kW rating develops 20 m with up to 520 L/min. The classic exterior design has long been recognized by the market, and the electrophoresis coating keeps the housing corrosion-resistant in service.

Why Choose FORWATER
When the requirement is volume — bulk transfer, irrigation mains, circulation loops — port size and flow rate decide the pump, and the DTM-E20B leads the DTM-E range with 3" (76 mm) ports and up to 520 L/min. Choosing between its two ratings is a matter of head: 15 m at 500 L/min for the 1.1 kW (1.5 HP) unit, or 20 m at 520 L/min for the 1.5 kW (2 HP) unit, both on the same body and pipework.
FAQ
What is the difference between the DTM-E20B and the DTM-E20A?
Port size and flow: the B model uses 3" (76 mm) ports and reaches up to 520 L/min, while the A model uses 2" (50 mm) ports and up to 450 L/min. Both are available in the same two power ratings.
How do I choose between the two power ratings?
Compare your duty point against the two performance tables above — 15 m / 500 L/min for 1.1 kW (1.5 HP), 20 m / 520 L/min for 1.5 kW (2 HP). Send us the required head and flow and we will confirm.
What liquid can it handle?
Clean water and liquids similar to water, with pH 6.5 – 8.5 and a maximum liquid temperature of ≤60 °C.
