Vehicle wash system including a variable speed single pumping unit
First Claim
1. A vehicle wash system comprising:
- a plurality of distribution manifolds for applying water to a vehicle during a wash process;
a variable speed pumping unit operable to supply a flow of water to the distribution manifolds, the variable speed pumping unit being operable at selectable speeds to vary the pressure of the flow of water to the distribution manifolds;
a motor drive coupled to the variable speed pumping unit for controlling the speed of the pumping unit; and
a wash controller coupled to the distribution manifolds to selectively permit the flow of water from the pump to enter into each of the distribution manifolds, wherein the wash controller controls the application of water to the vehicle by controlling the entry of the water into the plurality of distribution manifolds.

Abstract
A pumping system for a vehicle wash system in which the pumping system includes a single, variable speed pumping unit. The variable speed pumping unit includes a variable speed motor that is controlled by a variable frequency motor drive such that the single pumping unit supplies water at varying pressures to the vehicle wash system. The vehicle wash system includes a plurality of distribution manifolds that can be selectively opened to apply water and/or a chemical agent to the vehicle during the wash cycle. The variable speed pumping unit of the vehicle wash system is controlled by a wash controller such that the wash controller can selectively control the pressure of water flowing through the distribution manifolds.
