The Wilden diaphragm pump range is ably supported by a range of accessories that complement air operated diaphragm pump function & capability. Wilden’s accessory products add value to your liquid process and expand the application range of Wilden diaphragm pumps by augmenting the performance and/or utility of the pump. Our electronic controllers automate your Wilden pump for batching and other electronically controlled dispensing applications. We can also create laminar process flow by eliminating pump pulsation or control the liquid level within a system of process.
An inherent characteristic of reciprocating pumps is the pressure change between each pump stroke. The Equalizer® can be used to provide a supplementary pumping action between pump strokes, thus minimising pressure fluctuation while offering protection to your pumping system. The Equalizer® reduces water hammer, absorbs acceleration head, lowers system maintenance costs and minimises pipe strain protecting in-line equipment. Sizes available are SD1⁄2 13mm (1⁄2") inlet/discharge, SD1 25 mm (1") inlet/discharge, SD2 51 mm (2") inlet/discharge and SD3 76 mm (3") inlet/discharge.
The inherent features of the Wilden air-operated pump and Accu-Flo™ pump technology allow it to excel as a utilitarian drum pump. Various speed and pressure capability, the ability to run dry, self-prime and dead-head offers you flexibility at a low cost. The Wilden universal drum pump kit enables Wilden ¼” and ½” pumps to adapt directly to drums for cost-effective, efficient liquid transfer.
The Wil-Gard™ detects diaphragm failure at the source: the primary diaphragm, not at the air chamber or the air exhaust as other systems do.
The PCMI counts pump cycles by sensing the presence of the air valve piston (Turbo-Flo™) or air valve spool (Pro-Flo™).
The Wilden pump series consists of the following ranges:
All Pumps have a large stock holding of Wilden spares, including spare parts kits, and will always provide the right solution for you.
Some of the Wilden spare parts can also be used in other air-operated diaphragm (AODD) pumps such as ARO.
