Installation Planning
Inlet Piping
• Size the inlet line one or two sizes larger than pump suction
opening.
• Suction lines should be as short and direct as possible.
• Size the suction line so that the velocity will not exceed
1 – 3 ft/sec.
Velocity = 0.408 x GPM
Pipe ID
2
• Install a 3 ft. to 4 ft. flexible hose between pump and hard
piping to absorb vibrations, expansions, or contractions.
• Install an inlet pressure/vacuum gauge on the inlet side of the
pump.
• To reduce turbulence and resistance, do not use 90° elbows.
If turns are necessary in the suction line use 45° elbows or
long sweeping elbows when required.
• Install piping supports where necessary to relieve strain on
the inlet line and to minimize vibration.
• In extreme cases, a pulsation dampener may be required if
hard piped.
Discharge Piping
• Size the discharge line to at least one size larger than the
pump inlet connection.
• Between the pump and hard piping, install flexible a hose long
enough to reduce pulsations (typically 3 ft. to 4 ft.).
• Install a pressure gauge in the discharge piping.
• In extreme cases, a pulsation dampener may be required to
absorb excessive pulsation (caused by high pump speed and
long discharge lines).

! CAUTION
Important Precautions
• To avoid personal injury or pump damage, follow all
instructions and safety precautions carefully.
• Don’t exceed the manufacturer’s recommended RPM
or pressure limits.
• Follow all codes and hydraulic recommendations on
installation and operation of the pumping system.
• To prevent vibration, mount the pump and motor securely
to a rigid, level base.
• For safety and easier servicing, provide adequate work
space around the pump. Allow space to remove the front
cover, hose clamps, hose, and drive unit.

How to Use this Maintenance Manual
This technical manual covers the Vector 2000 Series pumps.
The manual provides instructions on how to install, start, and
maintain the pumps. All persons, installers, and users must
read the manual in its entirety prior to installation and use.
Your local Wanner distributor is also available for additional
information.
For a reply, please include the following information:
• Type of pump

Principle of Operation
Two rollers, mounted on a rotor, alternately compress a thick-
walled hose in a patented concentric guide. As they rotate, they
push the liquid in the hose from the suction to the discharge side.
The subsequent opening of the hose, after a roller passes, creates
a vacuum on the suction side — resulting in continuous pumping.
