Filter Pump
A division of Finish Thompson — filter chambers, Penguin Series vertical pumps, complete filter systems, and metal-free filtration media for corrosive plating and process solutions.
What LibertyCES specifies from Filter Pump
Cartridge, bag, and carbon chambers for alkaline/acidic solutions up to 230°F — no metal-to-liquid contact, flow to 200 GPM.
Same family, meaningfully different envelopes by material: P Series 280°F (CPVC/PP/PVDF) vs. PS 316SS -30°F to 211°F for caustics and chlorinated solvents.
ASF to 3,400 GPH; MF acid/alkaline systems handle precious metal plating, high chloride, sulfuric, and alkaline cyanide solutions.
50-micron nominal to 0.10 micron absolute pleated filters, plus 316SS or fully metal-less PM tank-drum mixers.
Frequently Asked Questions
What is the difference between Filter Pump P, PHF, and PS vertical pumps?
The P Series (CPVC/PP/PVDF) is rated to 280°F. PHF and PX are CPVC-only, rated to 180°F, with double-impeller self-priming and no seals/bushings to wear. PS is 316 stainless steel, rated -30°F to 211°F, built for cleaners, caustics, and chlorinated solvents.
What is the MR-SR Metal Recovery Chamber used for?
It recovers precious metals — up to 3 troy oz per pound of ion exchange resin — from rinse water and drag-out tanks in plating operations, and also improves rinse-water purity for reuse.
What micron range do Filter Pump pleated filters cover?
50-micron nominal down to 0.10 micron absolute, with DOE or SOE end caps and no surfactants or binders that could break down, leach, or migrate into the process fluid.
