KSB launches new Multitec pump with long service life

KSB Group has extended its Multitec pump series with the new Multitec DN 200 high-pressure pump, available with four different hydraulic systems and two to six stages.

The DN 200 is designed for casing pressures of up to 40 bar and suitable for use in water supply, irrigation, pressure boosting, or fire-fighting systems.

Its maximum head is nearly 400m and maximum flow rate is 850m³/h.

The pumps are driven exclusively by four-pole three-phase motors with a maximum power rating of 1000kW.

Running at 1450 or 1750rpm, the DN 200 pumps will reach the same maximum flow rate as higher-speed pump sets with smaller nominal diameters, yet run much more quietly.

Their low rotational speeds help reduce wear and have a positive impact on both the service life and the efficiency of the pump set.

Energy efficiency, a long service life, and low noise emissions are important to customers in the water sector.

The pump is able to handle liquid temperatures up to 60°C and has a maximum weight of 1.6 tonnes, with casings made of nodular cast iron and impellers made of bronze.

To cover a broad spectrum of applications, the pump sets can be equipped with a variety of standardised single mechanical seals or gland packings.

The diffusers can be supplied in grey cast iron or bronze, and their transition areas are protected against wear by casing wear rings.

The pump shaft is supported by ball bearings at both ends.

Multitec DN 200 offers a high degree of operating reliability at low energy and maintenance costs, due to its dimensions and being equipped with flow-optimised hydraulic systems.

The Multitec pump can be supplied for horizontal or vertical installation.
