Versa-Matic E5-½” Bolted Metallic AODD Pump

The Versa-Matic E5 ½” (13 mm) Bolted Metallic air-operated double diaphragm (AODD) pump is a compact industrial pump designed for controlled fluid transfer, OEM equipment, chemical dosing and other small-volume process applications.

With an adjustable flow rate up to 12 gpm (45.4 lpm), the E5 combines secure bolted construction with Versa-Matic’s non-stalling, lubrication-free air-valve system. The compact footprint and multiple material options allow the pump to be configured for a wide range of compatible industrial fluids.

Wetted constructions are available in aluminum, stainless steel and Alloy C. Multiple diaphragm, valve-ball and seat materials are also available to match different chemical compatibility, temperature and operating requirements.

Key Features & Benefits

  • Maximum adjustable flow rate up to 12 gpm (45.4 lpm)
  • Compact ½” pump for OEM and space-restricted installations
  • Secure bolted construction for reliable fluid containment
  • Non-stalling and lubrication-free air-valve operation
  • Reliable on/off response for intermittent process duties
  • Aluminum, stainless steel and Alloy C wetted constructions
  • Multiple diaphragm and valve-material configurations
  • Simple serviceability for reduced maintenance time
  • Suitable for controlled small-volume fluid transfer

Material Selection

Aluminum: A lightweight metallic option suitable for many general industrial fluid-transfer applications where the fluid is compatible with aluminum.

Stainless Steel: Provides enhanced corrosion resistance and is suitable for applications requiring durable metallic wetted components.

Alloy C: Provides additional corrosion resistance for selected aggressive chemical applications where compatibility has been confirmed.

ATEX Configuration

ATEX configurations are available for applicable hazardous-area installations. The pump and associated equipment must be properly grounded and installed according to the manufacturer’s instructions and applicable site requirements.
