Smith & Loveless Non-Clog Pump
4-Step Vacuum Priming Process
The Smith & Loveless Vacuum Priming System
is a simple proven 4-step process that includes just three basic components:
a prime sensor, a solenoid valve, and a vacuum pump.
| The wet well level sensor calls for the pump to start. | |
| The pump prime sensor determines whether
the pump is primed. If the sensor indicates the pump is primed, the pump turns on. Steps 3 and 4 are not required. |
|
| When Step 2 occurs
and the prime sensor indicates that the pump requires priming, the vacuum pump comes on and the solenoid valve opens. The vacuum pump evacuates air from the pump suction line and the pump through the 1/2" diameter vacuum tubing. This causes wastewater to fill the pump volute and prime the pump. |
|
| When the prime sensor indicates the
pump is primed, the solenoid valve closes, the vacuum pump shuts off and the pump turns on. This is all done in a few moments. Simply. Reliably. Dependably. Proven in more than 20,000 installations worldwide. |
From a totally non-primed condition, the system is designed to prime
the pump in about 60 seconds under standard rated conditions. Once the
Smith & Loveless Pump is primed, it is designed to stay primed indefinetly.
