SACI pumps single-stage centrifugal pumps designed in accordance with DIN-EN 733 (formerly DIN 24255). Cast-iron volute casing, dynamically balanced impeller, stainless-steel shaft (AISI 304 / AISI 420). Flow rate from 1 to 500 m³/h, head up to 100 m, motors 0,25–132 kW, fluid temperature -10 °C to +140 °C.
Motor mounted directly on the pump (monoblock), 2-pole motor, 2 900 rpm. Compact and easy to install. For applications requiring higher head at medium flow rates. PN 16 flanges in accordance with DIN 2533 (PN 10 for DN 200). Carbon/silicon carbide mechanical seal, EPDM O-rings. Operating pressure up to 16 bar.
Motor mounted directly on the pump (monoblock), 4-pole motor, 1 450 rpm. Lower speeds mean quieter operation, less wear, and a longer service life. For applications with high flow rates and lower head – circulation in heating, cooling, and air conditioning systems. Same design and materials as the NKP-G.
Pump and motor mounted on a shared steel baseplate and connected by a flexible coupling. Flexible motor selection – can be paired with any manufacturer and efficiency class. Available as a hydraulic section / wet end (bare shaft) or with a motor. For large industrial installations where flexibility in drive selection is required.

NKP-G – choose this if you need a compact pump with a higher head and medium flow rate. Typical applications include pressure systems and fire protection circuits.
NKM-G – choose this when low noise, long service life and high flow rate are priorities. Typical applications include HVAC and heating and cooling circulation systems.
KDN – for large industrial installations where you want to choose your own motor or need a bare shaft for a specialised drive.
DIN-EN 733 is a European standard for the dimensions and connections of centrifugal pumps. The NKP-G, NKM-G and KDN pumps have standardised flange dimensions and centre-to-centre distances – when replacing an old pump with a new one, you don’t need to modify the piping or foundations.
A 2-pole motor (NKP-G) runs at 2 900 rpm – delivering a higher head with the same impeller size. A 4-pole motor (NKM-G) runs at 1 450 rpm – it is quieter, has less wear and a longer service life, but requires a larger impeller to deliver the same head. A 4-pole motor is more suitable for HVAC and circulation, while a 2-pole motor is better for pressure applications.
Yes, both monobloc series can be installed horizontally or vertically, provided the motor is at the top. The KDN can only be installed horizontally.
Yes, a bronze impeller (GCuSn5Zn5Pb5) is available on request. It is suitable for seawater, mildly aggressive media or applications requiring greater corrosion resistance.
Clean, non-viscous, non-aggressive, non-crystallising, chemically neutral fluids, free from solid or abrasive particles and with properties similar to water. For other fluids, please consult us (a more powerful motor may be required).
