Maintenance
Important Safety
Information
The pump contains internal moving parts. DO NOT put hands or
fingers into the pump body ports or drive area at any time during
operation. To avoid serious injury, DO NOT install, clean, service,
or repair the pump unless all power is off and locked out and the
pump is de-pressurized. Shut off and drain product from the
pump prior to disconnecting the piping.
Maintenance should be performed only by trained personnel. See
“Qualification Guidelines for Operating Staff” on page 16.
Make sure the pump is securely bolted or clamped down prior to
performing any maintenance work. The pump center of gravity
changes as parts are added or removed, and could result in
tipping of an unsecured pump.
Make sure to keep the work area clear of machine parts, tools,
product lines, foreign materials, and power cables to avoid
potential hazards.
Make sure appropriate lighting is available: at least 1000 lux,
independent of daylight and weather conditions.
Before carrying out any maintenance and repair work on cold
components, ensure that the machine parts in question are
sufficiently heated. The contact temperature of accessible
machine parts must not be lower than those in the EN ISO
13732-1.
To lift the cover on a 210 or 320-U3, attach an eye bolt to the
threaded hole in the cover and attach lifting straps or chains to
the eye bolt.
To lift the body of a 130, 180, 210, 220, or 320-U3, use a lifting
strap threaded through the ports on either side of the body.
To lift the gear case assembly on pumps larger than 018-U3,
attach lifting straps/chains to the two eye bolts on the top of the
gear case.
Before detaching port connections to the pump:
• Close the suction and discharge valves.
• Drain the pump and clean or rinse, if necessary.
• Disconnect or shut off the electrical supply and lock out all
power.
The pump components and piping may
contain sharp edges. Handle the rotors
carefully because edges may be sharp.
Wear gloves while installing and servic-
ing the pump to help avoid injuries from
these hazards.
Never touch the gear case during opera-
tion. The surface temperature may
exceed 110°F (43°C). The pump cover
and body may be cold or hot depending
on the product (CIP at 190°F (88°C) or
300°F (149°C) product, for example).
