Autogas Pumps—Troubleshooting Guide

Pump Will Not Build Pressure

Possible Causes

 

What To Do      

Poor suction conditions Check the storage tank excess flow valve and clean filter screen. The suction pipe might be too small or restricted. Remove restrictions and/or increase pipe size.
Bypass valve set too low Set valve for higher pressure. See valve instruction manual.
Too much clearance on the impeller Impeller should be re-shimmed or replaced. Do a performance test on the pump. See performance curves for reference. See the preventative maintenance program in the Installation Operation and Maintentance (IOM) manual.
