Heating Circulating Pumps

In-Line Close-Coupled Canned Motor

Designed for providing forced circulation in hot water heating systems of individual houses and buildings (ETsL 2-3,5), communal power generation projects and industrial structures (ETsL 16-10), as well as for increasing the flow velocity (as accelerators for hot water). Used especially in heating plants at pumping temperatures up to 110C.
In-line horizontal shaft single-stage close-coupled canned motor centrifugal pumps (glandless pumps). Wet rotor motor and medium lubricated plain bearings. The in-line construction (of I-type) allows installing the motor pump into either the outlet or return line of a water circuit. Motor speed is controllable in three (ETsL 2-3,5) or two (ETsL 16-10) steps.

In-Line Close-Coupled

Designed for handling water (except sea water) and other liquids (similar to it by their density, viscosity and chemical activity) at pumping temperatures up to 120C.
Horizontal or vertical* shaft in-line close-coupled single-stage volute-casing centrifugal pumps with flange connections and additional support. Driven by hermetically sealed motors.
