Repair Kit for the R-Series Dia-Vac® Pump Single Head

This kit contains All-Teflon parts that (PN# 11011) includes:

• Diaphragm set, 3 layers of Teflon Diaphragms
• Small discs (x2) used as one-way valves in the heads
  
• Gasket for holding plate for the one-way valves

Specifications & Compatibility

• Part Number: 11011
• Material Construction: 3-ply 100% PTFE
• Weight: 0.1 lbs. (approximate)
• Applications: Corrosive chemical handling, laboratory sampling, and high-temp industrial use

Why Choose All-Teflon Diaphragms

• Maximum resistance – Pure Teflon resists strong solvents, vapors, and aggressive gases.
• High-temperature capability – Maintains structure in applications where blends degrade.
• Dependable operation – Provides long service life under harsh operating conditions.

The 3-ply Teflon kit provides the longest service life possible due the flexibility of the thinner, stacked layers of Teflon.  This kit uses all Teflon components to provide reliable operation with ozone gas streams.

Ideal Uses & Environments

• Ozone gas applications where a booster pump is required
• Groundwater remediation applications where high pressure may be requried for in-situ applications
• Research requiring higher pressures of ozone gas than an ozone generator/oxygen feed-gas source can provide
• Vacuum driven ozone generators, the compressor allows the ozone generator to be operated under a vacuum, while providing pressure to the point of use.

FAQs

How long do all-Teflon diaphragms last?

Service cycles average 6 to 12 months, depending on operating conditions. Regular inspection every 4 to 6 months is recommended.

What can shorten diaphragm life?

Excessive pressure, high heat, moisture, and corrosive gases all contribute to wear.

How long does replacement take?

With OEM kits, installation can usually be completed in under 15 minutes.
