Wilden has designed its Advanced Plastic Series A100P air-operated double-diaphragm pumps (AODD) to deliver high performance and efficiency while meeting the required abrasion, temperature and chemical-compatibility parameters.
The A100P is a 13 mm (1/2-inch) pump that features a bolted configuration that helps ensure total product containment. Additionally, its redesigned liquid path can reduce internal friction to maximize output and efficiency. The pump delivers flow rates up to 42.4 lpm (11.2 gpm) with a maximum pressure of 8.6 bar (125 psi). It has a maximum dry-suction lift capability of 6.6 mm (21.5 inches) and can handle solids with a diameter of 1.6 mm (0.06 inches). Elastomer options include Buna-N, polyurethane, Saniflex, PTFE, Viton and Wil-Flex.
Accu-Flo technology helps maximize the operation of the A100P. This technology employs a two-position, four-way solenoid valve that has a single operator and spring return, allowing the valve to be internally air-piloted for longer coil and operator life. Air pressure fills air chambers and displaces the diaphragms with electrical impulses dictating the stroke rate. By alternately applying and removing electrical power, the Accu-Flo pump reciprocates back and forth similar to standard air-operated pumps, contributing to increased pump efficiency.
