PXU140 Owner’s Manual

2. Installation
2.1 Precautions
Handling
Do NOT lift pump by proximity cables, quick exhaust valves nor air tubing.
Installation Orientation
PXU140 pumps must be installed in an upright position. Check valves are actuated by gravity and/or flow and will not seat if the pump is not upright. Do not install pumps within 3 ft of each other or it may interfere with proximity sensors.
Timer Mode
PXU140 pumps require an end of stroke detection mechanism (pressure switch) to prevent over stroking in timer mode. Operating a PXU140 in timer mode without stroke detection will void the pump warranty.
Required Air Flow (Shuttle Valve)
PXU140 pumps require 3/8 in minimum orifice with unrestricted air flow.
Required Air Flow (Solenoid Valve)
PXU140 pumps require a 3 Cv solenoid. Using a reduced Cv will reduce flow rates. Using a valve with more than 20% greater Cv will change operating parameters, reduce pump life and void the warranty.
Under Supply of Air
PXU140 pumps operate erratically or stall when air supply is insufficient. Ensure use of air supply pressures higher than averaged air consumption lines in performance charts. Air supply lines and fittings must meet minimal inner diameter requirements shown in the installation instructions.
Air Supply Pressure
Operating PXU140 pumps ~35% below max air pressure may significantly extend pump life. PXU140 pumps require 20 psi minimum air pressure. Operation above 7 Bar (100 psi) may damage the pump and void the warranty.

Using Proximity Sensors
Pumps using a proximity sensor are not intrinsically safe and do not qualify for use in explosion-proof environments.
Suction Lift
PXU140 pumps have initial suction lift of 3 ft. For best results minimize suction lift.
Liquid Inlet/Outlet Connections
PXU140 liquid ports are not NPT nor any other standard. Use of connectors other than those supplied by White Knight will damage the pump and void the warranty.
Liquid Line Restriction
PXU140 pumps may be controlled by closing liquid outlet lines. However, restricting liquid supply lines increases wear and should be avoided. Do NOT pump against a closed liquid inlet. It will damage the pump and void the warranty.
Running Dry
PXU140 pumps use the pumped liquid to lubricate their shafts. The pumps will cycle faster and wear more than normal when run dry, which may cause damage and loss of self-prime abilities. PXU140 pumps should not be run dry after startup and are not warrantied under dry run conditions.
Pulse Dampener with Shuttle Valve
Air supply pressure to PXU140 pumps should be at least ten psi higher than the liquid line pressure when using a pulsation dampener. Failure to do so may cause erratic operation.
Cross Contamination
PXU140 pumps use porous material that may retain chemicals. Take precautions to avoid cross contamination.

PXU140 Owner’s Manual

2.2 Warnings
Pressurized Material
Pumps in use contain pressurized materials. Eliminate liquid and air pressure via shut off valves before pump is serviced or removed from the system.
High Temperature
Heat may transfer to exterior surfaces when pumps operate with high temperature fluids. Avoid direct contact with the pump when high temperature fluids are present.
Hazardous Chemical
Use appropriate personal protective equipment when handling pump. Reference Material Safety Data Sheet (MSDS) for information specific to your chemicals.
Loud Noise
Pump exhaust air contributes to work area noise levels. Only operate pumps with approved muffler media, and use ear protection in noisy conditions.
2.3 Advantages
Head Pressure / Dead-Head
PXU140 pumps can be controlled by adjusting their liquid outlet pressures and can be installed with head pressures up to dead-head (e.g. equal liquid and air pressures) with no damage to the pump.
Thermal Cycling
PXU140 pumps require no maintenance when operated within their performance range, even in thermal cycling applications.

2.4 Environment & System
Oversized Inlet Line
Pumps operate optimally with liquid inlet lines larger than the liquid outlet lines. This reduces strain on the bellows and may reduce pulsation in the pump outlet.
Clean Supply Air (CDA)
PXU140 pumps require use of Class 2 air for particles and moisture per ISO 8573-1. Use 10 micron filter; maintain -40°C dew point. A point-of-use filter is recommended during first six months of operation in new fabs/systems due to high risks of debris that can damage pumps and void warranty.
Flammable Solvents
PXU140 pumps are not constructed from conductive materials. System that pump flammable solvents should be properly grounded to avoid ignition by static charge. A River’s Edge test of isolative pumps with flammable liquids indicated that liquids must be grounded and other procedures should be followed. Copy of test available.
Pumping Liquids Near Boiling Point
Minimizing suction lift reduces pulsation and the potential for boiling or outgassing of liquid in the inlet of the pump. Although reciprocating pumps can pull suction lift, pump performance and life increase when suction lift is minimized or eliminated.
Abrasive Slurry
Pumping abrasive slurry may accelerate wear of components. PXU140 pumps are warrantied when used with slurry. However, normal wear is not covered by warranty.
Environmental Temperature
PXU140 pumps are rated for 0°C (32°F) 50°C (122°F) environmental temperatures. Do not freeze fluid in pump. Operation below 0°C may accelerate wear. Normal wear is not covered by warranty.

a Class 2 source of supply
· Use of Proximity Sensors does not qualify for intrinsically safe environments.

3.2 Shift Logic for Proximity Pumps

Air must be sent to either side at startup to initiate movement.

Pump Startup

During pump operation, the timing of the solenoid valve should be dependent on sensors with no time delays. There should be no delay between reading the sensor signal and actuating the solenoid valve.

Send air to left side
of pump

Check Sensors

Send air to right side
of pump

Logic

Only left sensor is true

Only right sensor is true

Air remains on either side if both sensors are true or false

Proximity End Stroke Operation

The proximity sensors on the pump can both be seen in the middle of the stroke; thus it is required that the solenoid not be switched until just one sensor is seen. * Vertical line denotes when the solenoid was switched.

Remove leak adapter and leak detect probe from fiber optic assembly.
For straight out configuration replace NPT plug in “L” port with the probe. Hand-tighten.
Insert the fiber optic cable until it contacts the bottom of the probe.
Lower ferrule and gripper until snug against the probe. Hand tighten female gripper nut.
For elbow out configuration:
Open the top and slide the front face of the D10 up. Press the fiber optic ends into the holes on its front. Slide the face down to lock cables in place.

Proximity switch ordered separately. Proximity switch is required for operation. Standard configuration does NOT include proximity switch. For applications requiring the NPN signal, White Knight recommends the use of a signal converter similar to Balluf part number BAE002H.
Timer mode operation requires end-of-stroke detection. Use of timer mode without stroke detection voids the warranty. Operating the pump without the included quick exhaust valves (QEVs) voids pump warranty. Customers may use their own QEVs with the optional NPT adapter.
