NR Multi-row pumps

Design:

Single impeller centrifugal pumps with direct motor-pump connection and common shaft. The pump housing (multi-row version) has suction and delivery sockets of the same diameter and located on the same shaft.

Application:
Pumping of clean liquids that are not aggressive to materials and do not contain abrasive impurities from which the pump is made (solids content max. 0.2%). Use in household and industrial areas. If necessary, work with a reduced noise level (n = 1450 rpm). Use in heating, air conditioning, cooling and circulation installations.

Operating limits:
- Maximum allowable final pressure in the pump casing: 10 bar.
- Continuous operation.
- Fluid temperature from -10°С to +100°С.
- The ambient temperature is not more than 40°С.
- Manometric suction lift no more than 7 m.
