Versa-Matic E1-1″ FDA-Compliant Bolted Metallic AODD Pump

The Versa-Matic E1 1″ (25 mm) FDA-Compliant Bolted Metallic air-operated double diaphragm (AODD) pump is designed for food-processing and sanitary fluid-transfer applications requiring reliable operation, hygienic construction and FDA-compliant materials.

The pump features stainless steel wetted construction with internal and external surfaces electropolished to 150 µ-in (Ra 3.81 µm). Sanitary 1½” Tri-Clamp fluid connections support quick disassembly, cleaning and reassembly for food and beverage processing duties.

With a maximum flow rate of 49 gpm (185.5 lpm), the E1 FDA pump is suitable for filling, blending, ingredient transfer, product transfer and other hygienic process applications. ATEX-compliant configurations are also available where required.

Typical Applications

  • Food ingredient transfer
  • Filling lines
  • Blending and mixing
  • Ingredient injection
  • Product transfer
  • Tank transfer and overflow duties
  • Beverage-processing applications
  • Small-batch food production
  • Applications requiring FDA-compliant materials

Cleaning & Sanitary Processing

The E1 FDA pump uses electropolished stainless steel wetted surfaces and sanitary Tri-Clamp connections to support easier dismantling, cleaning and reassembly. This makes the pump suitable for food-processing applications where frequent sanitation is required.

Cleaning chemicals, cleaning temperature and sanitation procedures should always be checked against the selected diaphragm, valve and wetted-material configuration.

ATEX Configuration

ATEX-compliant E1 food-processing configurations are available for applicable hazardous-area installations. The pump and connected equipment must be correctly installed, bonded and grounded according to the manufacturer’s instructions and site requirements.
