WARNINGS, CAUTIONS & NOTICES

Please read all cautions, warnings and notes
completely before installation and start-up.
It is the responsibility of the purchaser to retain this

WARNINGS

To prevent static sparking the pump, piping,
valves, and containers must be grounded.

CAUTIONS

You must check the tightness of all hardware
prior to installation.

Maximum temperature limits are based on
mechanical stress only. Certain chemicals

will signicantly reduce maximum safe operating

temperatures. For chemical compatibility and temperature limits
please refer to the Chemical Resistance Guide.

Check temperature limits for all wetted
components when choosing pump materials.

Temperature limits may vary depending on the material.

manual for reference. Failure to comply with the
recommendations stated in this manual may damage
the pump and void the factory warranty.

Pump exhaust may contain contaminants that
can cause serious injury. Take precautions
to pipe exhaust away from work area if pumping

chemicals, hazardous or ammable materials.

Do not exceed the maximum inlet air pressure
as stated on the pump model tag.

Disconnect the compressed air line to the
pump and allow all air pressure to bleed
from pump prior to performing any maintenance
on the pump. Disconnect all intake, discharge and

air lines. Drain the pump and dispose of uid into a

suitable container.

All operators of the equipment should
be properly trained to ensure safe working
practices.

The process uid and cleaning uids must be
chemically compatible with all wetted pump
components. Please refer to the Chemical Resistance Guide for

additional information.

Thoroughly ush pump before installing into
process lines. FDA and sanitary approved pumps should

be cleaned or sanitized before use.

NOTICES

Blow out air line for at least 15 seconds
before attaching to pump to make sure that all debris

is removed. Use an in-line air lter.

Clamp style pumps tted with PTFE or XLTPE
come standard from the factory with expanded PTFE liquid
chamber gaskets. PTFE gaskets cannot

be reused.

Tighten both outer pistons at the same
time to ensure a tight t when installing
PTFE diaphragms. See torque settings for additional details.

Never allow the piping system to be supported
by the pump manifolds or valve housing. These

components are not designed to support structural weight and pump
failure may result..

Noise levels can exceed 85 dBA.

Always wear ear and eye protection when
operating or repairing pumps.

Compressed air should not be applied to
the exhaust port. If this happens the pump will not

function.

Before disassembly of clamp band pumps,

mark a line from each liquid chamber to its
corresponding air chamber. This will ensure proper

alignment when reassembling.

The pump does not require continuous
lubrication.

INSTALLATION, OPERATION & MAINTENANCE

Installation Pump Operation

The pump should be mounted in a vertical
position. In permanent installations, the pump should be
attached to plant piping using a exible coupling on both the
intake and discharge con­nections to reduce vibration
to the pump and piping. To
further reduce vibration, a

pump may
be used.

as the inlet connection size,
even larger if highly viscous

Make certain the air supply line and connections

Air that is contaminated with moisture and dirt
may result in erratic pump performance and
increased maintenance cost as well as frequent

The pump is powered by compressed air.
Compressed air is directed to the pump air

4 Valve ball(s)/seat(s) damaged or attacked by product
5 Clogged suction line

Recommendation(s)

1 Reinstall pilot o-rings in correct positions
2 Reinstall inner diaphragm plate correctly
3 Check system for pressure ratio to pump
4 Install gaskets with holes properly aligned

1 Set lubricator on lowest possible setting or remove

• Elima-Matic is designed for lube free operation
2 Check the air line size and length, compressor

capacity (HP vs. cfm required)

3 Replace o-rings
4 Check compatibility of o-rings with lubrication
5 Clean air valve/lter
6 Clean suction or discharge manifolds/piping
7 Reinstall o-rings in correct position
8 Increase air supply pressure

1 Check suction condition (move pump closer to product)
2 Clean out around valve ball cage and valve seat area

• Replace valve ball or valve seat if damaged

• Use heavier valve ball material
3 Worn valve ball or valve seat

• Worn ngers in valve ball cage (replace part)

4 Check Chemical Resistance Guide for compatibility
5 Clean suction manifold and/or piping
