Booster Pumps

How to choose

The correct pump must move the required water through the actual plumbing system without exceeding the filter’s rated flow. Start with pool volume and turnover, then confirm total dynamic head, voltage, pipe size, controller requirements and service clearances.

Horsepower is useful only after those constraints are understood. Two pumps with the same nominal horsepower can produce different flow at the same head, use different connections and behave differently at low speed. Always compare the manufacturer curve and installation manual for the exact model.

Buying framework

1. Establish the flow requirement

Divide pool gallons by the desired turnover hours, then by 60. Treat that number as a starting point, not the final answer. Suction length, fittings, elevation, filter pressure, heater restriction and water features all change the operating point.

2. Protect the filter

A pump that can deliver more flow than the filter or plumbing can accept may create noise, high pressure and poor efficiency. The system’s safe limit is set by its most restrictive component.

3. Compare lifetime cost

Purchase price is only one part of ownership. A controllable pump operating near its efficient range can cost less over time than an inexpensive pump that runs at full speed for every task.
