Patented, replaceable rotor skirt bushing provides high pressure operation while reducing overhung loads. On both packed box and mechanical seal heavy duty models, the throttle bushing located directly behind the roto provides additional shaft support and seal cavity throttling.

Computer designed gear teeth profile provides quiet, smooth pumping flow. Standard high strength gear material eliminates the need for special steel fitting.

Unique internal pressure lubricated idler pin reduces wear by continuously cooling and lubricating the idler pin and bushing.

Seal cavity venting provides continuous flow of liquid through seal cavity, ensuring cooling. It also maintains seal cavity at low pressure reducing seal face load and increasing seal life.

Deep end feed area offers improved performance under low inlet pressure conditions and/or high vicosity liquids.

Unique back pull-out design allows service and maintenance without disconnecting pump housing from piping.

O-ring design on relief valve allows for adjustment during operation, without leakage.

Foot brackets are centrally located under pump ports, providing better pump and piping support. Multiple center line height enables simple and inexpensive bases.

Interchangeable 90º or 180º housings with multiple port sizes on most models. Eight different port positions in 45º increments make installation faster and easier.
