Filter Press Diaphragm Pumps

Filter Press Diaphragm Pumps
Diaphragm pump mounted to filter press manifold and catwalk.

Air operated diaphragm pumps are used with filter presses to pump sludge from the bottom of the sludge holding tank into the filter press.  These pumps are ideal because they can handle the slurry which is generally about the consistency of a milkshake. 

The diaphragm pump usually starts out slowly and gradually ramps up.  Once the pump starts to slow back down, (30-60 seconds between thrusts), it is usually an indicator that the filter press is full.  At this point the feed pump should be turned off and the valves on the filter press closed as the operator prepares to operate the air-blow-down process.

The diaphragm pump can be manually turned up or an Automatic Pump Control system may be added.  This starts the pump at 25 psi, then moves up to 50, 75 and finally 100 psi which is standard operating pressure for the pump.

Met-Chem provides diaphragm pumps in the following sizes:  1”, 1.5”, 2” and 3”.  Material of construction ranges from cast iron, aluminum, polypro or stainless steel.

With the purchase of a new Met-Chem filter press Met-Chem can mount your air operated diaphragm pump to the legs of your filter press.  This option also includes a flex hose that connects the outlet of the diaphragm pump to the center feed pipe, an air filter, a regulator, and an oiler.   We can also provide a mounted diaphragm pump for your existing press. 

Filter Press Options:

Water Treatment Case Study: A Clean Lagoon is a Good Lagoon: Fiberboard Manufacturer's existing system could not handle the volume of paper pulp being generated.  They needed to clear out the sediment that was accumulating in their lagoon that were in violation of environmental regulations.

Waste Water Treatment Systems Case Study: Just to clarify…: A new boarding school needed to put in a self-contained sanitary waste treatment system to handle all water sources generated at their facility. Met-Chem designed and built two 120 GPM clarifiers with flocculation tanks, and custom catwalks built to fit space limitations and overlook and operate the waste treatment system.
