GRACO 25R052 – 4 Valve KRAKN MPI fluid manifold assembly, Class 1, Division 1 approved for Hazardous

GRACO 25R052 – 4 Valve KRAKN MPI fluid manifold assembly, Class 1, Division 1 approved for Hazardous Locations, 3000 PSI

4-point KRAKN MPI fluid manifold assembly designed for hazardous locations (Class 1, Division 1). This smart, simple, and robust fluid manifold can replace up to eight chemical pumps with just one when used in conjunction with chemical pumps. Features solenoid valve options for hazardous locations and maintains flow rates and pressures across remaining injection lines even when one line is down for service.

Replace up to eight chemical pumps with just one when used in conjunction with the KRAKN MPI fluid manifold. Pair it with Gracos Harrier+ MPI control box and chemical pumps for best dosing accuracy.
