Valley Head Services Oil Pump Service

HOME > Oil Pumps

Since building our first Geroter dry sump pump in 1967, Valley Head Service has continually tested and improved these pumps until they have become the finest and the most reliable on the market today. Here are some of the advantages:

The VHS Geroter type external dry sump pumps are positive displacement and produce a greater pan vacuum the conventional gear type pumps. Because of this, they leave less oil in the crank case to fly around and reducing the amount of horsepower robbing windage.
All VHS dry sumps are tested on our exclusive certified oil pump flow bench and the external bypass valve is pre-set to 70 lbs pressure. The bypass valve can be adjusted to compensate for bearing clearance or to the engine builder’s requirement.
The VHS Geroter type pump utilizes less moving parts, therefore, requiring less horsepower to drive the system. Once the system is initially primed, it stays primed and maintains a positive displacement each revolution throughout the entire RPM range.
All parts of the VHS dry sump pump are built from billet materials, not a casting or an extrusion. The fact ensures maximum strength, lightweight construction and close tolerances between all mating parts. Each pump stage is “O” ringed to prevent leaks.
VHS Dry Sump Systems include the best parts and accessories available on the market today; Redhorse Performance fittings and hoses, Patterson Enterprise Oil Tanks, Oberg Filters, and Gates Belts.

In the unlikely event that you do hurt one of our pumps, it can usually be repaired in minutes by using a small file or stone to dress off the high points until the pump turns freely. Vane or gear type pumps typically cannot be salvaged without new gears or housing.

The VHS drive system is very light and yet extremely sturdy to prevent any pump flex. We offer drive systems for all common installations and can make custom units for any application.

The Time-proven GEROTER design is tough and simple. It also requires less power to drive than a vane or gear driven pumps. That saves power for the race.

Most popular in marine use, a single stage pump is also great when you have the need to lower your engine in the chassis without decreasing your sump volume. An external pressure adjustment allows adjusting the pressure to your needs. By using good pan baffling, you can enhance the windage tray and sump separation to reduce power-robbing excessive oil splashing around in the crank case.
