Application GuidanceApplications
Guidance for the services that ruin ordinary pumps. Each page explains why the service is hard, which approaches get specified, and how we confirm a selection before quoting.
Pumps for Sodium Hypochlorite (NaOCl)How to select a pump for sodium hypochlorite service: why bleach destroys standard pumps, what sealless thermoplastic and metering options exist, and how RE Merrill confirms materials before quoting.Pumps for Hydrochloric Acid (HCl)How to select a pump for hydrochloric acid service: why HCl and its fumes defeat metal pumps, what sealless thermoplastic options exist, and how RE Merrill confirms materials before quoting.Pumps for Sulfuric Acid (H2SO4)How to select a pump for sulfuric acid service: why concentration changes everything, what thermoplastic and sealless options exist, and how RE Merrill confirms materials before quoting.Pumps for Sodium Hydroxide (NaOH, Caustic Soda)How to select a pump for sodium hydroxide service: why caustic soda destroys seals and freezes in lines, what sealless and dosing options exist, and how RE Merrill confirms materials before quoting.Pumps for Ferric Chloride (FeCl3)How to select a pump for ferric chloride service: why this common coagulant destroys metal pumps, what thermoplastic and metering options exist, and how RE Merrill confirms materials before quoting.Pumps for Phosphoric Acid (H3PO4)How to select a pump for phosphoric acid service: why grade and solids content decide everything, what thermoplastic and sealless options exist, and how RE Merrill confirms materials before quoting.Pumps for Wastewater pH NeutralizationPump selection for wastewater pH neutralization systems: dosing acid and caustic against a moving target, handling variable waste streams, and how RE Merrill confirms the equipment before quoting.Pumps for Semiconductor Ultrapure Water (UPW)Pump selection for semiconductor ultrapure water: why UPW attacks the equipment that carries it, why metal ions are the enemy, and how RE Merrill confirms purity-critical selections before quoting.Chemical Transfer Pumps for Processing PlantsPump selection for chemical transfer duties: railcar and tote unloading, tank-to-tank transfer, and why the utility pump from stores fails in chemical service. How RE Merrill confirms selections before quoting.Pumps for Metal Finishing and PlatingPump selection for metal finishing and plating: pickling acids, plating baths, rinse water, and effluent. Why the plating room destroys ordinary equipment, and how RE Merrill confirms selections before quoting.
