WORKING PRINCIPLE
2SI pumps are centrifugal pumps, designed for permanently or partially immersed operation to produce higher dynamic head. The working principle is that of three-stage centrifugal pumps. The three impellers are installed on the same shaft and rotate inside vane diffuser, channelling the fluid from each impeller to the suction opening of the next. The fluid passes through the three impellers and leaves the pump via the delivery opening machined in the pump body. Between impellers and vane diffuser form a pumping stage and increase the liquid pressure efficiently, following the principle of centrifugal machine.
PUMP INSTALLATION AND APPLICATIONS
This pump is suitable for pumping or fluids. Their higher performance and dependability make them suitable for use in domestic, civil and industrial fields, for the automatic distribution of water working in conjunction with surge tanks, for emptying basins, tank, sump pits, swimming pools and aquariums, for irrigation gardens, for washing and pressure-boosting system, and for fire-fighting purposes, etc, where need higher dynamic head.
PERFORMANCE
Pump combines the advantages of a submersible pump with the performance of a centrifugal pump. In fact they assure:
¡ù outputs having higher absolute values
¡ù ample and particularly stable curves
STRUCTURAL CHARACTERISTICS
¡ù cast iron pump body
¡ù stainless steel mechanical seal (graphite to ceramic or SIC to graphite)
¡ù stainless steel shaft
¡ù with float switch or without
¡ù with thermal overload protector in single phase motor |
