| Problem:
Spill prevention due to failure of diaphragm in AODDP |
| |
| Accidental spills of chemicals and
other dangerous fluids can be hazardous to workers and
equipment. Even a small spill can be expensive to clean
up. |
| |
| Solution: |
| The Warren Rupp RuppGUARD Spill Prevention
offers the highest level of safety when pumping aggressive
fluids. |
| |
| Spill Prevention models feature fluid-filled
PTFE or PVDF spill chambers, with additional diaphragms
between the air end and each outer pumping chamber. All
Plastic Series spill containment models are equipped with
visual leak detectors, which immediately warn the pump
user if a pumping diaphragm fails. Two additional leak
detection options include electronic and manual monitors. |

Standard
Visual Leak Detection
This standard feature gives a visual warning when a problem
occurs. If the pumping diaphragm fails, pumped liquid
enters the spill containment chamber. This displaces driver
fluid in the spill containment chamber. The exchange of
pumpage and driver fluid displays a color change in the
sight tube on the side of the pump which has failed. |
| |
Optional
Electronic Leak Detection
The electronic leak detection option senses polarity changes
in the spill containment chamber. These changes occur
when pumpage contaminates the driver fluid. The electronic
leak detector activates a warning light on the control
box. It can also be wired into an end-user's existing
warning system for audible alarm or pump shut-down. |
| |
Optional
Mechanical Leak Detection
The mechanical leak detection option uses a spring-loaded
connector pin and o-ring. The o-ring material, which is
specified to be chemically incompatible to the pumped
fluids, swells when a leak occurs. The o-ring reaction
triggers release of pilot air through an air control valve,
signalling a diaphragm failure. |
