Mac 26

This hydrostatic test pump is engineered for both hydrostatic testing and high-pressure chemical injection applications, the Mac-26 weighs in at 175 lbs. The hydrostatic test pump is designed using power piston size 6", stroke length of 2", cycles/minute adjustable to 100, max input pressure at 100 psi, and a power gas max cons of 51 SCFM. The Mac-26's temperature limits are from -20 to 140F. Materials chosen for maximum corrosion resistance. This reciprocating pump has reduced components for easy maintenance. Positive displacement, stroke rate adjustment for accuracy.
Optional single head simplex
