Filter Press Diaphragm Pumps

Filter Press Diaphragm Pumps


Air operated diaphragm pumps are used with trickle 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 normally starts out lento and gradually ramps up. Once the pump starts to slow back down, ( 30-60 seconds between thrusts ), it is normally an index that the filter press is fully. At this point, the fertilize pump should be turned off and the valves on the trickle crusade closed as the operator prepares to operate the air-blow-down procedure.

The diaphragm pump can be manually turned up or an automatic rifle Pump Control system may be added. This starts the pump at 25 psi, then moves up to 50, 75 and ultimately 100 pounds per square inch which is standard operating press for the pump .
Met-Chem provides diaphragm pumps in the watch sizes : 1 ”, 1.5 ”, 2 ” and 3 ”. The material of construction ranges from hurl iron, aluminum, polypro or stainless steel steel .
With the buy of a new Met-Chem percolate imperativeness, Met-Chem can mount your atmosphere operated diaphragm pump to the legs of your filter press. This option besides includes a flex hosiery that connects the wall socket of the diaphragm pump to the center feed pipe, an vent filter, a regulator, and an oil well. We can besides provide a mounted diaphragm pump for your existing press. Center Feed and Manifold Filter Press Upgrades

Filter Press Center Feed and Manifold Upgrades

Stainless steel center feed and manifold piping for corrosive solutions. A center feed pipe assembly on a trickle press should be able to last many years the same way any other type of plumb will. however, if the substantial of the center feed shriek assembly is not solid adequate to handle the corrosiveness of the solution running through the press then the center fertilize pipe fabrication can corrode .
For cases of caustic corporeal or high temperatures, Met-Chem is pleased to offer upgrades from our criterion center feed pipe and manifold. We are able to upgrade to CPVC, Carbon Steel, 304 or 316SS Stainless Steel, and Titanium. Met-Chem can besides provide extra manifold upgrades such as automatic pistol valves
The center feed pipe is what connects the filter press to the product that needs to be filtered. The center field tip organ pipe fabrication consists of five different parts. The first part is the lock nut which fastens on the center feed shriek and connects to the outside of the press. The shriek, which is the second part, goes through the mind of the filter and all the room through the head plate of the trickle press. The third part of the plaza feed pipe forum is a gasket which ensures the assembly is watertight. next, is the cartridge holder testis seat which fastens the fabrication to the head plate. This region of the assembly will constantly stay in place unless you are replacing the assembly or one of its parts. The final separate, the fabric nip nut, will be removed often as it is screwed into the fabric clip addict seat after the heading fabric is put on the head plate. The fabric clip crackpot needs to be tightened in order to keep the fabric in position. Met-Chem provides a tool to make this process easier. The Met-Chem Spanner Wrench is a particularly designed tool that can be used to loosen and tighten the fabric time nut when changing the head fabric on a filter press. This tool can be very helpful as the fabric time, but it has a invention that requires a singular tool to tighten and loosen it. Sludge Dumpster

Filter Press Sludge Dumpster

Filter Press Dump CartSludge Dumpsters are used directly under the filter press to catch the sludge that is released from the filter press during cleaning.  The dumpster is on casters for easy mobility.  They are also equipped with forklift slats for convenient use with a tow motor.  The operator can move the dumpster to a roll-off container with the forklift and then pull the release pin for easy emptying.  The dumpster can then be snapped back to the upright position and put back under the filter press. sludge Dumpsters are used immediately under the filter press to catch the sludge that is released from the trickle iron during cleaning. The dumpster is on casters for easy mobility. They are besides equipped with forklift slats for convenient manipulation with a tow drive. The operator can move the dumpster to a roll-off container with the forklift and then pull the secrete pin for easily empty. The dumpster can then be snapped spinal column to the upright position and put rear under the percolate wardrobe. spare Parts Kit

fifth wheel Parts Kit

Filter Press Spare Parts Kit Met-Chem is pleased to offer our spare parts kit which includes our 5 man center feed pipe assembly, a headway, tail, and 2 intermediate filter press cloths, and 100 foot of gasketing substantial. These are necessity items for the mathematical process of the filter press. A crack pipe, ripped fabric, or tear gasket can happen anytime and having these items in your store will ensure you will be back up and running in no time . Precoat system

Skid-Mounted Precoat Station


Skid-Mounted Precoat Stations are custom built to work with any filter imperativeness ( minor changes in the plumb may be required ). The basic precoating system includes a skid-mounted platform with a holding tank, mixer, controls, and a diaphragm pump. The precoat place can besides be used as an Acid Wash System to clean filter cloths and maintain high levels of filtration. The basic precoating mathematical process involves mixing a slurry of percolate help, normally a combination of water and Diatomaceous Earth. The slurry is then pumped into the Filter Press and then recirculated into the holding tank. This process is run until the liquid appears to be clear or until the appropriate depth of precoat is achieved. Skid-Mounted Precoat Stations can be customized and operated differently depending on the process of your specific application. Contact us for advice on the benefits of these portable skid-mounted systems.

Some Features and Options for your system may include : Automatic Filter Press Pump Control System

Automatic Filter Press Pump Control System

Automatic Pump System Control Panel Automatic Pump System Control Panel gradually increases the pump atmospheric pressure up to 100 PSI for standard units. This allows for even filling of the filter chambers .

The Met-Chem Automatic Pump Control System is used in concurrence with an air operated diaphragm pump to mechanically increase the feed pump coerce at preset intervals during the trickle press filling bicycle. If the pump runs at a higher initial atmospheric pressure, the filter patty will become a throng layer of solids on the filter fabric. This will restrict the flow of the slurry thereby creating a very dense application of the percolate cake. This can cause the cloths to blind off and not allow further filtration. Starting at a lower feed blackmail allows a soft layer of slurry particles to be deposited on the percolate fabric. This initial layer becomes the trickle media which will enhance the filterability of the entrance slurry .
The automatic pump command system automatically and gradually increases the feed atmospheric pressure in four stages during the meet bicycle. These stages are adjustable to suit your slurry and solids concentration. however, it is normally set at increments of 25 psi. ( 25, 50, 75, 100 ). By monitoring the feed pump hang detector, during the final examination pressure stage, the hustler will be able to determine the cycle completion .
The Automatic Pump Control System besides incorporates a low hydraulic imperativeness condom shut down the device. If there is not adequate hydraulic clamp pressure present, the arrangement will completely shut down, eliminating any possible leak from between the percolate plates .
The pump control system allows your filter press to run at its optimum efficiency creating dry trickle cakes, reducing disposal costs, reducing operator clock and increasing the life of your filter cloths and prey pumps .
This organization can be incorporated with a modern filter press from Met-Chem, a use whole or flush your own exist press. Longer Legs and Filter Press Sludge Disposal Chute

Longer Legs and Sludge Disposal Chute for Filter Presses

Met-Chem can provide longer legs and a administration parachute on your new trickle weigh. This is specially utilitarian if you are releasing the sludge from the crusade into a sludge cup of tea or a cram. The parachute will direct the sludge directly into your container. If you plan to use a sludge disposal bag, we can add hooks to the chute so that the sludge pocket can be hung from the frame of the press .
For some larger presses, we can build a catwalk along with the administration chute in order to accommodate a roll-off container .

Filter Press Backer Plate for Smaller Batches

Removable epoxy coated steel backer plate allows the operator to vary the operator to vary the holding capacity of the filter press. If you produce varying size batches of effluent and subsequently less sludge, or if the overall volume of neutralize that is generated at your facility has been reduced, you can inactive utilize your existing filter weight-lift. With the leverage of a angel plate, you can alter the holding capacity of your press to meet your individual batch needs .
A angel plate provides support to the tail plate so that it can be moved anywhere in the plate pack in order to isolate the chambers between the run end and the chase plate. If you try to use the chase plate in a different status in the home plate pack without the angel plate, you run the hazard of damaging the bedroom of the fag end plate .
There are unlike kinds of backing plates. Some are made of formative and look much like a criterion plate ; we prefer to use ~3/8 ” thick flat malcolm stock steel and cut an draft of a plate. This is clearly visible when placed in the stack so that all about know that the filter press is not at entire capacity. This steel backing plate is then painted with the same bipartite epoxy coat as the skeletal system of the filter press. Filter Press Plate Shifters

Filter Press Plate Shifters

Our standard filter presses can be operated manually. however, Met-Chem manufactures four types of filter weigh plate shifters to make operating your filter press easier, safer and more effective. manual filter presses require more time and attention than the same filter urge with an automatic rifle plate gearshift .

  • Semi-Automatic
  • Pendant
  • Fully Automatic
