Hy~Line and Ultima Lobe Pumps - Jabsco - #39

Text version of the page

Pumps are also available with enlarged rectangular (hopper) inlet - Fig 1. This is used for pumping liquids which are so viscous that they will not flow through any inlet pipe fast enough to fill the pump at the desired running speed. The largest possible opening is machined in the side of the rotor case to allow a hopper (not supplied with pump) to be bolted directly to the face. Alternatively, an auger screw feeder can be adapted to this face to force product into the pump inlet. Rectangular Inlet pumps are normally supplied assembled for vertical pipe orientation. The weight of the hopper (and the product it contains) must be supported separately and not allowed to rest entirely on the pump as this would affect the rotor clearances leading to pump seizure. Dimensions of rectangular inlet: The mating flange of a hopper or screw feeder should be machined to the identical dimensions to avoid ledges where product could .hang up.. The position of the centre line of the hopper inlet is the same as the centre line of the port. See below. The enlarged inlet port is on the right side of the rotor case when viewed from the front cover of the pump. (top shaft drive) For dimensions of the hopper inlet see overleaf.
