In order to meet specialized pumping problems this variable volume pump requires less HP by maintaining a minimum pressure, adjusts its displacement to the discharge rate allowed and reduces the breakdown of materials being pumped in a recirculating system. In "Filling" applications this pump is superior being that during "Deadheading" the pumping members go into neutral and idle delivering nothing but holding the operating pressure on the discharge line thus absorbing a fraction of the HP required during operation. The energy saving, depending on the operation can be significant.
This top suction side discharge pump is designed for semi-solid and high viscosity applications and when equipped with in stock flow and/or pressure controls allows the operator to adjust the delivery of the pump from maximum down to zero without the need of changing pump shaft speed. In so doing the pump is capable of handling wide ranges in viscosity from grease, adhesives, oil additives, compounds, coatings and the like even down to near water thin liquids
