HORIZONTAL MULTI STAGE PUMPS

Transcription

1 HORIZONTAL MULTI STAGE PUMPS APPLICATIONS Water supply Hot/cold water Sprinklers Agriculture Construction Factories Mines Boiler feed Other general high pressure services *Please choose the model, referring to specifications for each model. FEATURES EBARA s unique double volute construction provides higher operating efficiency over a wide range of capacities than conventional pumps equipped with a guide vanes. Simple construction of the pumps contributes to longer service life. The pumps are compact, lightweight and operate with minimum of noise. Double volute casing designed to balance radial force at all range of operation. Axial force is absorbed by a balance-disc which has a wear indicator at shaft end. Parts are fully standardized to ensure easy servicing and maintenance. The pumps are designed so as to not exceed rated horse power at any pumping quantity. (MS10) SELECTION CHART

FEATURES OF DOUBLE VOLUTE CONSTRUCTION 1. As shown in the drawing, water flow is divided into two equal parts by tongues A and A, located 180 apart. This produces a symmetrical flow to the section which is at right angles to the shaft and rationally balances radial thrust on the motor.. Basic studies and experiments determined that shape and contour of vortex must introduce vertical flow directly to the impeller of next stage. This feature, plus the meticulously designed three dimensional impeller, enables MS pump to achieve incomparable efficiency.. Casing configuration, which is narrower than that of conventional multistage pumps, contributes to the design of a light-weight, compact double volute pump.
