Repair Kit for B Series Dia-Vac® Pumps
B Series Dia-Vac® Pumps
When you need a compact vacuum pump for low flow gas sampling, the B Series Dia-Vac® is a proven choice. These light duty, single head diaphragm pumps deliver reliable performance without oil, oversized housings, or complicated hookups.
ADI Kits focuses on keeping those pumps running. We stock OEM B Series Dia-Vac® repair kits, including the 11461 All Teflon Diaphragm Repair Kit, along with manuals and application resources. That makes it easy to specify the right B Series pump configuration, identify the correct diaphragm repair kit, and service your units in a single visit.
What Are B Series Dia-Vac® Pumps?
Air Dimensions, Inc. (ADI) makes B Series units. These are light-duty, single-head diaphragm pumps. They are designed for low-flow gas sampling.
Portability, low power use, and oil-free vacuum operation are very important. Typical flow range is 1–7 L PM at up to 25 inHg vacuum—ideal for:
- Stack testing & ambient air surveys
- Portable continuous-emissions monitors (CEMs)
- Internal Analyzer Pump OEM cabinet integration for analyzers or FTIR cells
Because the diaphragm never uses lubricating oil, B Series Dia-Vac® pumps virtually eliminate the risk of hydrocarbon contamination in the sample stream. When paired with an OEM diaphragm repair kit, you get a clean, dependable gas path that is simple to maintain.
Key Features & Benefits
B Series Dia-Vac® pumps are built for technicians who carry their lab in a field case and cannot afford leaks, noise, or complicated service. Every design choice supports fast, reliable sampling and straightforward repair kit replacement.
The highlights below show why B Series units have become the go-to compact diaphragm vacuum pump for environmental consultants, CEM specialists, and OEM analyzer builders alike.
Compact Footprint
At just 5.4 × 4.1 × 5.6 inches (W × H × L) and under 4 lb, the B Series slides easily into portable sampling cases or crowded analyzer panels.
Oil-Free, Clean-Gas Path
PTFE-faced (Teflon®) diaphragms and valves keep sampled media pure and resist aggressive gases—no messy oil changes, no vapor back-streaming.
Low Power, Multi-Voltage
Standard brushed-DC motors draw only 0.9 A at 12 VDC (other voltages available), extending battery life in the field. Optional 115/230 VAC motors simplify setups.
Quiet & Cool
Direct-drive diaphragm motion runs quiet with minimal heat rise—important for on-person instrumentation and temperature-sensitive analyzers.
Built for Serviceability
Four socket-head screws release the pump head and valve body; complete diaphragm swap or valve cleaning takes <5 minutes with an OEM Dia-Vac pump parts kit.
Why Repair Instead of Replace?
Pumps wear over time, but that doesn't mean you need a new one. With the right diaphragm, valve, and gasket replacements, most B Series Dia-Vac pumps can operate for years.
ADI Kits carries only genuine, field-proven OEM parts that match the exact performance specs your equipment was built on. No generics. No guesswork. Just the right kit for the job.

Lightest Form Factor
30% smaller than J-Series heated-head versions.
Cost-Effective
Entry-level price point without sacrificing ADI's diaphragm reliability.
