Hydraulic Pump/Motor  

Torvec has redefined the science of hydraulics. The result is the Torvec Hydraulic Pump and Motor — the major breakthrough behind the Torvec Infinitely Variable Transmission (IVT™).

Pump / Motor

These pumps and motors have a place of their own in the industrial pump market. Current hydraulics suffer from critical problems:

  • Rotating piston group
  • Inefficient valving
  • Hydraulic whine
  • Heavy housings

Existing pumps need to be large and heavy in order to deliver the desired power. The size and weight prove detrimental in automotive design, as valuable space and weight are eaten up by the hardware.

Torvec innovation led to the design of their own Hydraulic Pump. Torvec has eliminated the rotating piston group (the cylinders are stationary), making the pump tremendously powerful and easy to manufacture.Torvec's patented valving has been integrated to increase efficiency and reduce noise (hydraulic whine).

The challenge was to deliver the necessary power while reducing the size and weight of the pump, using parts that can be manufactured at high volume and low cost. The design solution resulted in a pump with extremely high power density (horsepower to weight ratio), at less than half of the industry standard weight for a comparable hydraulic pump. For example, most 12 cubic inch displacement pumps range from 200 lbs - 270 lbs, while Torvec's 12 cubic inch displacement pump weighs in at approximately 75 lbs.

The reduced size and cylindrical shape of the hydraulic pump allows for easy packaging in automotive applications. The tremendous power delivered by the Torvec Hydraulic Pump also lends itself to many industrial applications. Torvec management is pursuing every market for this truly revolutionary pump.

Why the Torvec Pump?

The Torvec Pump is lighter and smaller than existing comparable pumps, and can easily be packaged for automotive use.

Unique and patented systems within the pump deliver an extremely high power density while eliminating hydraulic "whine."

A two-pump configuration provides the framework for Torvec's revolutionary Infinitely Variable Transmission (IVT™).

The Torvec Pump has many industrial uses, and the power to deliver.
