Minimise Diaphragm Replacement Downtime
Downtime is one of the most expensive realities in pump operations. In many facilities, the root cause isn’t the pump – it’s recurring diaphragm failure from low-end PTFE designs that can’t handle aggressive media, abrasion, pressure cycling, or high-duty service.
The Real Cost of Cheap Diaphragms
Inexpensive diaphragms may look like savings upfront, but they often lead to:
- Frequent failures and unplanned shutdowns
- Repeated pump removals and workshop repairs
- Lost production time and reduced output
- Increased labour, freight, and maintenance costs
- Maintenance teams stuck reacting instead of planning
Each failure compounds cost – parts, labour, and lost throughput – because the diaphragm becomes the weak link.
Why Diaphragm Reliability Matters
The diaphragm is the heart of an AODD pump. When it fails, the system stops – often due to fatigue, cracking, or rupture under abrasive slurries, solids, viscous fluids, chemical exposure, and cycling pressures.
The Garlock ONE‑UP® Diaphragm Difference
Garlock ONE‑UP® diaphragms are engineered for demanding duty using a high‑performance GORE® ePTFE sheet on the wetted side, physically bonded in a one‑piece composite to a premium fabric‑reinforced elastomer backer. Patented rib/surface features help disperse stress for longer flex life. Field case histories report ~3.5× longer average service life than conventional PTFE; one paint/coatings site increased life from 1–3 months to ~18 months across 200+ pumps.
Where ONE‑UP® Fits Best
- Abrasive slurries and high solids
- Chemically aggressive media (acids and caustics)
- Highly viscous fluids (paints, coatings, resins)
- High pressure cycling and harsh AODD service
Performance Notes (for Specifying)
- Chemical resistance is broadly suited to media in the pH 0–14 range (with stated exceptions such as molten alkali metals and elemental fluorine).
- Temperature performance depends on pump dynamics; OEMs advise re‑rating speed/pressure for low/elevated service temperatures – general guidance commonly referenced is 40°F–200°F (4°C–93°C).
- FDA/CIP/SIP options exist: GYLON® ONE‑UP® (GY part numbers) with EPDM backing is listed as CIP & SIP capable to 300°F (149°C); ONE‑UP® may also be used in potentially explosive atmospheres when installed in ATEX‑compliant pumps.
More Than a Product — A Reliability Solution
More than a replacement part, ONE‑UP® supports a reliability approach: application assessment, correct selection for duty conditions, and practical installation guidance.
