In-line pumps

Construction

Close-coupled, single-impeller, centrifugal pumps; electricmotor with extended shaft directly connected to the pump.

NR, NR4 series: Single head electropumps.
NRD, NRD4: Twin head pump with built-in automatic switching valve. The two head can operate singularly or in parallel.
Pump casing with suction and delivery connections with the same diameter and on the same axis (in-line).
Version with frequency converter (on request)

Application

For clean liquids without abrasives, which are non-aggressive for the pump materials ( solids content up to 0.2%).
For heating, air-conditioning, cooling and circulation plants.
For civil and industrial applications.
When low noise operation is required (n ? 1450 rpm).

Operating conditions

Liquid temperature from -10 °C to +90 °C.
Ambient temperature up to 40° C.
Total suction lift up to 7 m.
Maximum permissible working pressure up to 10 bar.
Continuous duty.
