This new generation pump, Siera, is a state-of-the-art horizontal multistage close-coupled centrifugal pump, which its entire hydraulic wet-ends are manufactured from stainless steel - AISI 304 or AISI 316.
Adopting a unique stamping process, the end product is one of superior quality and efficiency to meet today's sophisticated application requirements in the building services and the general industries especially when a higher head is required.
The unique pressing technology that revolutionised the pump design concept, coupled with the AISI 304 or AISI 316 pressed stainless steel hydraulic wet-ends, leads to higher operating efficiency over a wider range of capacities and lowers operating costs.
Siera is supplied with IP55 weatherproof rating, IEC standard, aluminium frame, TEFC type electric motors. NEMA frame motors can be fitted as option.
To facilitate the purging of trapped air in the pump.
Centreline-discharged design ensuring maximum resistance to misalignment and distortion from pipe loads. The volute casing is designed as an integral part of the pump body.
All wetted parts are produced in high quality polished pressed stainless steel, which offers excellent corrosion resistance and increased durability. The smooth uniform surface ensures optimum performance, maintaining high efficiency throughout pump life and lower power consumption, hence lowering operating cost. Depending on the medium to be handled, Siera offers two main variance of material of construction. The wetted hydraulic parts of Model SR is constructed in stainless steel. For more aggressive medium, Model SRX offer SS316-grade construction.
