Inline Constant Pressure System
INSTALLATION
Location of the Inline Constant Pressure System
Decide on a location for the pump installation that is suitable based on the enclosure rating of the
Inline System.
Liquid-tight conduit and fittings must be used to maintain NEMA 4 rating.
This equipment must not be used by children or persons with reduced
physical, sensory or mental abilities, or lacking in experience and
expertise, unless supervised or instructed. Children may not use the
equipment, nor may they play with the unit or in the immediate vicinity.
Choose a clean, well-ventilated location that provides protection from freezing, flooding, and
excessive heat. In addition, it should provide access for servicing and allow convenient draining of
the pump, tank, and service pipes. A prepared foundation is not essential, provided the surface is
hard and level. It can be mounted in any orientation depending on the space available.
Installation in direct sunlight can reduce system power and reduce
drive life.
Plumbing, Piping, and Hoses
In general, keep the suction and discharge lines as large as possible. Avoid using bends, elbows,
and fittings whenever possible. All suction connections must be airtight, so use pipe compound on
all threaded joints. Use a suction strainer when applicable to prevent solids and foreign matter from
being drawn into the pump.
Flow Capacity by Pipe Size
The minimum supply pipe diameter should be selected not to exceed a maximum water velocity of
8 ft/sec (2.4 m/s). Use the table below for selection of the proper supply pipe size.
Water Supply Requirement
The Inline System is not designed to draw/lift water from a source below the pumping unit. There is
not an incoming flow requirement, other than that the system needs to be supplied with a constant
supply of water to keep the unit completely full of water at all times. It is recommended that the
system be supplied with inlet line ¾" diameter or larger.
