Overview
The Inline SpecPAK is a zero-footprint, multi-pump pressure boosting system for commercial, industrial and multi-residential plumbing. It arrives packaged and ready to install: you give the required flow and the constant pressure you want, and the pumps adjust speed to hold that pressure as demand changes.
The parts on this page are the system’s own components and field additions: suction and discharge headers in 304 stainless steel with 3 in or 4 in grooved connections and grooved couplings, 316 stainless full-port ball valves and 303 stainless inline spring check valves, 150# flanged pump connections, the UL Type 1 control panel with its 7 in colour touchscreen, main and heavy-duty quick disconnects, transformers, and vibration isolator kits sized by system.

Before You OrderTell us the SpecPAK model and how many pumps are on the skid. Headers, isolator kits and transformers are sized per system, and a header from a duplex will not fit a triplex. Several of these ship LTL.
