A pressurised inlet on a hand pump becomes an issue at higher pressures as the operator is working against an additional handle load. There are also significant safety issues when the handle moves suddenly due to a high applied inlet pressure.
Our Micropac MH Tandem Pump is perfectly balanced on pressurised inlets. For applications such as filling fire extinguishers with CO2 (carbon dioxide) or other cylinder refilling, these units have been successful.
