moving both low and high viscosity liquids

ranger pump features

Smooth Operating Helical Gears

• Heat treated ductile iron helical gears provide silent, efficient long service life.

• Finely keyed and machined gears are easily replaced by sliding on and off the mainshaft.

• Friction and vibration are kept at a minimum by careful machining of the meshing helical gears.

Extended-life Wearing Services

• High lead bronze, iron or carbon bearings are available.

• Pumping gears are supported by four heavy duty sleeve bearings to prolong service life.

• Special machined grooves in the bearings allow both circulation and lubrication for lower bearing temperatures.

• Special outboard drive shaft bearing absorbs thrust loads and helps support external radial loads.

Precision Ground Shafts

• Induction hardened bearing and packing surfaces on precision ground steel shafts extend pump life.

• Hardened stainless steel shafts are available for specific installations.

Rugged Cast-iron Castings

• Maximum pumping efficiency is gained from quality castings machined to high tolerances.

• Positive alignment of the faceplate case and backplate is insured by large hardened steel dowel pins.
