Mac 28 single stage

This pump is designed as both a hydrostatic test pump and for high-pressure chemical injection pump applications. Net Weight : 475 lbs. Mac - 28 Single Stage - Power piston size is 8", stroke length is 4", cycles/minute are adjustable to 100 PSI. Power gas max cons are 185 SCFM and its temperature limits are -20 to 140 F. Positive displacement, Stroke rate adjustment for accuracy, and materials chosen for maximum corrosion resistance. This reciprocating pump has a compact design compared with alternate electric pumps. Reduced components for easy maintenance.
