- Record the installed HMD/HMT/HMQ designation and diaphragm count before identifying the diaphragm assembly. [source]
- Identify the preformed diaphragm together with the installed diaphragm control and monitoring arrangement. [source]
- Record whether the fitted valve execution is ball, cone or the OEM-labelled Reverse Valve option. [source]
- Record the actual housing execution; the HM page lists nodular cast iron, stainless steel, rubber-lined and polypropylene options. [source]
ABEL HM Piston Diaphragm Pumps (HMD / HMT / HMQ): Wet-End and Nameplate Identification
HMD, HMT and HMQ use two, three and four diaphragms respectively. HMT is a single-acting triplex configuration. Preserve the complete HM type and valve execution from the machine records.
Identify the installed design before enquiry
ABEL HM piston diaphragm pumps are designed for abrasive process media. The family includes HMD, HMT and HMQ configurations with preformed diaphragms and diaphragm control/monitoring. Identify the installed HM configuration and valve type before requesting parts.
