Economical, Simple Design Pumps for Medium-Duty Applications

Materials of Construction
  • Cast iron

 

 

Design Features

General Purpose Pumps are available in foot mounted versions (shown above) or compact C-flange mounted versions (Click here to view).

The General Purpose Pumps utilize a simple and economical "floating rotor" design, in which the rotor/shaft is not retained by a thrust bearing, and is allowed to "float" within the pump head.  This reduces the available pressure and allowable viscosity compared to a thrust bearing design like the Universal Seal or Heavy Duty series, but is well suited to many medium duty applications.

Depending on the model and size, sealing options include packing, component mechanical seals or lip seals.

Some models are available with optional UL listing for Fuel Oil, for use in the assembly of power-operated oil burners or for use as oil-transfer pumps for No. 6 or lighter fuel oil (Series 432-X, sizes C - HL, and Series 456-X, sizes C - FH).

The General Purpose Series includes the following models:

  • 32 - Cast Iron Packed Pumps
  • 432 - Cast Iron Mechanically Sealed Pumps
  • 432-X - UL343 Listed Cast Iron Mechanically Sealed Pumps
