A range of versatile, energy efficient bearing frame pumps, suitable for horizontal or vertical mounting and incorporating the Hidrostal Screw Centrifugal Impeller.
Hidrostal offers three distinct end suction pump designs. All designs are suitable for horizontal or vertical mounting.
The direct flange mounted motor is spigoted onto the bearing frame and eliminates the possibility of shaft misalignment. As additional security, a flexible coupling is also employed. The units are suitable for horizontal and vertical mounting and the back pull out design means the complete rotating unit, including the motor, can be simply withdrawn for inspection and maintenance of the hydraulic end. Available for pumps with discharge sizes of 50 to 700 mm (2 to 28″).
The close coupled end suction bearing frames are identical to the direct coupled ones but with a free shaft end. The units are suitable for horizontal and vertical mounting. Available for pumps with discharge sizes of 50 to 700 mm (2 to 28″).
The long coupled end suction pumps are of a traditional design, offering robust construction and long reliable service for both vertical and horizontal mounting. The standard construction has grease lubricated bearings, and oil lubrication can be provided on horizontal units to meet the requirements of process industries. The bearing housing is of modular construction, permitting various arrangements of mechanical seals to be used. The shaft end bearings have been selected to be used with belt drives and yet maintain long bearing lives.
