Italian pump manufacturer SAER is going to release its latest catalogue which includes the introduction of new sizes and types of its close coupled IR pumps for water management.
The new issue includes more than 800 models in 2 and 4 poles, with outlets from DN32–DN200 and power ratings from 0.37–90 kW. The new models include a super duplex version, in addition to the cast iron, stainless steel AISI 316, bronze and spheroidal cast iron models. The new sizes offer 2 and 4 poles for power up to 90 kW and there is a version with an IE 4 efficiency motor.
The IR pumps are also offered with an inverter on the motor board up to 15 kW, which regulates the rotation speed of the motor, modifying the performance of the pump to adapt to the conditions of use. A pump equipped with an inverter has several advantages, including less wear of mechanical components and a reduction of water hammer risk on the system. This reduces the pump’s life costs and offers energy savings with minimal impact on the environment.
