Four Position Casing |
Discharge can be located in any of four positions. Casing is close grain iron of 30,000 psi minimum tensile strength. Back pull-out design eliminates the need to disturb piping should the pump ever require service - the casing stays in the line. Openings are provided for test gauges, for venting and for draining the pump. |
Casing Wear Ring |
Prevents wear on casing and is easy to replace. |
Easy To Service |
Taking out only 4 cap screws allows removal of pumping assembly without disturbing piping. |
Mechanical Shaft Seal Information |
