Pump manufacturer ABEL says it recently landed a major order for three HMQ membrane piston pumps to be fitted at one of the largest silver mines in Latin America.

On site, these HMQ pumps (Hydraulic Membrane Quadruplex pumps) are used to transport mine water pumped from a shaft at a depth of 700 m at around 80 bar to the surface into a reservoir.

The HMQs are quadruplex-acting piston diaphragm pumps and manage high flow rates up to 450 m³/h, according to ABEL. They are primarily made for applications like transfer of tailings, mine dewatering and backfilling in mines.

In addition to mining, ABEL’s HMQs are also frequently used in the wastewater industry to transport sludge or feed filter presses.
