Background: A commercial pool filtration system must handle a wide range of operating conditions. Each cycle is subject to a large number of operational changes dependent upon pump, filtration type, flow (GPM), bather load, and environmental conditions. When selecting a pump for a pool application, the selection must be sized to handle the turnover rate for the pool as required by Health Dept Code 3124B. The pump’s primary design point is sized to operate against the most demanding condition in the filtration cycle – basically the dirtiest filtration point just prior to backwash. The pump is selected to deliver the design point as efficiently as possible. Unfortunately, when the filters are clean the pump will be operating against a total head of 10 PSI to 15 PSI (23’ to 35’) less than designed. This results in the pump operating for extended periods of time at the most inefficient position on the performance curve and at the same time the place most like to result in damaging cavitation. Cavitation is the sudden formation and collapse of low pressure bubbles in liquid by means of mechanical forces. Cavitation not only causes the pump to under perform but also is very damaging to the impeller and internals of the pump shortening the life of the equipment. The introduction of the H2O Smart Pump Control System (SPCS) into the system will result in the pump operating at the optimal design point and will also result in less wear and tear on the pump. This ends up savings thousands of dollars in energy costs over the life of the equipment and extends the life of the equipment. Definition: The Smart Pump Control System (SPCS) is a control device that works in tandem with existing or new Automatic Filter Controls (AFC) and Chemical Controls (CC). The SPCS responds to two different inputs, one is from a pressure transducer installed in the downstream return line to the pool, and the second is from the relays within the AFC or CC. After receiving the inputs, the SPCS then controls the speed of the motor causing the pump to operate where it was selected and designed, and also maintaining the required turnover rate for the pool. The SPCS constantly monitors these inputs and responds to the changing demands of the filter system throughout normal use, backwash, or shut down. This results in the best possible efficiency during operation with minimally detrimental operation to the equipment.
