Key Specs
−Dealer-direct Rola-Chem. Chemical touches the tube, never the pump.
Max Output
38 GPD
Voltage
120V or 240V
Pump Type
Peristaltic
Max Pressure
30 PSI
The Pro Series 305 steps up to 38 gallons a day, which is where high-bather-load commercial pools and larger acid-feed duties land. Three-roller head, the same tube-only chemical path, and enough output that the timer usually sits well below 100%. Because the chemical only ever touches the tube, there is no seal, no diaphragm and no valve for chlorine or acid to attack — you replace a pinch tube instead of rebuilding a pump head.

Before you order
Confirm the supply voltage at the pump location and whether your conduit or cord entry is required by local code. Check that your chemical is compatible with the tube material you order — clear Tygon for chlorine, black Tygon for acid. This pump is a metering device, not a transfer pump.
This product is offered in 6 configurations. Choose the power & connection and tubing that matches your installation before adding to cart — configuration is set at the factory.
