Geartek Hydraulic Gear Pump and Motors

General Description

The Geartek name has become synonymous with quality, delivery, and service. Geartek pumps and motors are designed and manufactured to combine the reliablility and economical features of external gear design with modern engineering and materials to produce true pressure ratings up to 4000 psi.

Product Information

Geartek has positioned itself as a major supplier to OEM’s of off-highway construction, mining, industrial, oil field, forestry, and marine gear pumps and motors. Still, Geartek is not too big to supply manufacturers requiring custom built, small run, or out of production pumps and motors. Specialty items, such as internal control valving in the units, are commonly available.

Geartek incorporates the basic design philosophy – “DO IT RIGHT THE FIRST TIME”. Many options with other brand pumps are standard with Geartek. Standard items for Geartek units include double fluoroelastomer shaft seals with indicator hole, PTFE coated pressure compensated thrust plates, combination 2 & 4 bolt SAE mounting flanges, field changeable rotation without extra parts, and a wide selection of shaft and porting options. Single, multi-section, and piggyback units are all standard configurations with Geartek.
