CALPEDA END SUCTION CENTRIFUGAL PUMPS

N / N4 Series – Single‑Stage EN 733 Pumps

These standard-compliant end-suction pumps are offered in two variants: N at 2 900 rpm and N4 at 1 450 rpm. Flow capacity ranges from 2.4 to 480 m³/h with heads up to 95 m and power to 75 kW. The Back-Pull-Out design allows dismantling without disturbing alignment. Available in cast iron or bronze, with mechanical seal or stuffing box options, they operate at up to 8 bar. Typical uses include water supply, heating, cooling, fire-fighting and irrigation in clean-fluid applications.

NM / NMD - Close‑Coupled Centrifugal Pumps

Close‑coupled pumps with threaded ports. NM is single‑impeller, NMD offers dual impellers for higher pressure performance. They handle flows from 1 to 66 m³/h and heads up to 114 m at motor power up to about 9 kW. Constructed in cast‑iron or bronze and suited to water supply, HVAC, irrigation and firefighting.

NM / NMS - Close‑Coupled Centrifugal Pumps

These models feature flanged connections. NM covers flows up to 480 m³/h, heads up to 95 m and power up to 75 kW. NMS incorporates a stub-shaft motor construction with integrated thrust bearings to support higher motor sizes. Built with axial suction and radial delivery, they comply with EN 733 standards.

NM4 / NMS4 - Close‑Coupled Centrifugal Pumps

These 1 450 rpm versions offer quieter operation for low‑noise installations. Specification and construction mirror NM and NMS models, designed for clean liquids up to 0.2% solids with optional bronze variants for enhanced corrosion resistance. Due to their lower rotational speed, they are best suited to applications where quieter operation is required (e.g. in residential, commercial or hospital buildings) and reduced wear and longer service life are desirable.
