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.
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 I.D.
• 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 to
decrease acceleration head.
Discharge Piping
• Size the discharge line to at least the size of 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).
Limited Warranty
Wanner Engineering, Inc. extends to the original purchaser
of equipment manufactured by it and bearing its name, a
limited one-year warranty from the date of purchase against
defects in material or workmanship, provided that the
equipment is installed and operated in accordance with the
recommendations and instructions of Wanner Engineering,
Inc. Wanner Engineering, Inc. will repair or replace, at its
option, defective parts without charge if such parts are
returned with transportation charges prepaid to Wanner
Engineering, Inc., 1204 Chestnut Avenue, Minneapolis,
Minnesota 55403.
This warranty does not cover:
1. The electric motors (if any), which are covered by
the separate warranties of the manufacturers of these
components.
2. Normal wear and/or damage caused by or related to
abrasion, corrosion, abuse, negligence, accident, faulty
installation or tampering in a manner which impairs normal
operation.
3. Transportation costs.
This limited warranty is exclusive, and is in lieu of any
other warranties (express or implied) including warranty of
merchantability or warranty of fitness for a particular purpose
and of any noncontractual liabilities including product
liabilities based on negligence or strict liability. Every form
of liability for direct, special, incidental or consequential
damages or loss is expressly excluded and denied.

! 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.
