Hydraulically actuated diaphragm pump | PHL Series

Improved component durability, easier to prime, performs more efficiently and it is safer and simpler to maintain.

The liquid end has been specifically designed for optimal chemical delivery. Available in metallic or non-metallic materials, the liquid end features a high-quality double ball check valve for repeatability and accuracy, micrometer capacity control for precise dosage adjustment, and a bleed system for safer maintenance and easier commissioning.

PHL pump is a high-performance, hydraulically driven diaphragm pump designed to API 675 standards, ensuring precision and reliability. It offers a steady-state accuracy of ±1%, repeatability of ±3%, and a 10:1 turn-down ratio for precise flow control. Featuring a sliding crank mechanism for positive stroke return, the pump allows accurate flow adjustment via a 10-turn knob and enables stroke adjustment while running or stopped. Built with robust cast iron construction, it includes oil bath lubrication for durability and high-precision check valves. The liquid end is available in SS-316 (with other materials on request), supports temperatures up to 150°C, and offers threaded or flanged end connections. Capacity adjustment is available through a lockable micrometer (standard) or an optional variable speed drive.
