The 4524-043 AC Variable Speed Drive constant pressure pump system matches motor speed to system demand. As more liquid is needed, the motor responds to increase flow. Conversely, as the demand lessens, the motor slows to a "super quiet" speed, always retaining a constant system pressure. The result is exceptionally stable flow and reduced amp draw. The Flojet AC VSD sensor-controlled pumps provide stable, constant-pressure operation on any AC application. Operation from no flow to maximum flow is proportionally controlled, eliminating unwanted pump switch cycling and the need for an accumulator tank.
Set up for hardwire installation, does not have a three prong AC plug. Please enter the "4524-500 Three Prong" option to the "notes" field while checking out, for a factory installed 3 prong outlet plug. An extra $20 will be added to your order total. (Wiring on your own 3 prong outlet plug may void the manufacturers warranty.)
A 20 mesh strainer minimum is required (40 mesh is better) on the inlet as debris will damage the pump internals. Failures due to foreign debris are not covered under warranty.
Pump does not include an inlet strainer/filter. There are a number of configurations available. See our inlet strainer/filter section under 'water system parts' if you require one.
Does include 1 pair of 10/13 mm hose barb x quad fittings. See our inlet/outlet fittings section under 'pump repair parts' if you require different quad fittings.
