The Shurflo Revolution Pump is NOT a variable speed pump.
It runs at speed on demand and discharge pressure is controlled via an internal bypass valve......bypass starts opening at 35 psi and is fully open at 55 psi.
This reduces pump on/off cycling and helps maintain a more constant flow.
The Extreme Series Pumps are variable speed and use a circuit board and microprocessor.
