Water circulation centrifugal pump
max. 700 m³/h | NHL - HPL, HPR, NHM series DICKOW PUMPEN KG

General

DICKOW-Hot water circulation pumps, type NHL and HPL, have been developed for medium and large sized heating plants, for heating calanders, presses, large buildings and other applications which require temperatures > 140°C.

The design of the NHL / HPL - pumps is based on long years experiences in the field of handling hot water and grants high availability and reliability in operation. Discharge diameter up to 200 mm, maximum capacity 700 m³/h (3100 gpm).

Construction

The NHL /HPL-types are single stage volute casing pumps in "back pull out" design with end suction and to centerline discharge flange. The "back pull out" design allows disassembling of the rotating pump part without removing the volute casing from the piping system.

For fully utilizing the advantage of the "back pull out" design, use of spacer-type couplings is highly recommended because the driver can remain bolted to the base plate.
