Pro-source PS-MK25AL Diaphragm Pump 42 Gpm 120 Psi

Product Description

The PRO-SOURCE PS-MK25AL is a 1/2-inch air-operated double-diaphragm pump built for industrial and commercial fluid transfer applications. It delivers a maximum flow rate of 42 GPM and handles working pressures up to 120 psi. The aluminum body keeps overall weight manageable at 10 pounds while standing up to demanding service conditions. Diaphragm and ball components are Hytrel, and the check seats are stainless steel, giving the pump solid chemical resistance across a broad range of media. It accepts solids up to 0.16 inches in diameter and operates up to 176 degrees F, making it suitable for moderately aggressive fluids in process, maintenance, and fluid-handling operations.

The PS-MK25AL is designed for industrial maintenance, light chemical transfer, wastewater, and general-purpose pumping tasks where a reliable, air-driven solution is required. The 1/2-inch NPT air inlet connects to plant air systems, consuming up to 6.74 CFM at rated conditions. Inlet and outlet ports are 1-inch NPT, keeping installation straightforward in both new and retrofit piping runs. Licensed plumbers, pipefitters, and industrial maintenance technicians are the typical installers for this class of pump.

Key Features

• 42 GPM maximum flow rate suits high-volume fluid transfer tasks
• 120 psi maximum working pressure for use in pressurized process lines
• Aluminum body with Hytrel diaphragms and balls for broad fluid compatibility
• Stainless steel check seats for extended wear life
• Handles solids up to 0.16 inches in diameter without clogging
• 1-inch NPT inlet and outlet ports for standard pipe connections
• Air-operated design eliminates the need for electrical power at the pump

Compatibility

Designed as an OEM-style replacement or direct-fit air-operated double-diaphragm pump for industrial fluid-handling systems with 1-inch NPT piping and a 1/2-inch NPT compressed-air supply.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or industrial maintenance technician following applicable facility safety procedures and local plumbing codes. Isolate and depressurize all connected piping and shut off the compressed-air supply before making any connections or removing the pump from service. Use thread sealant rated for the media being pumped on all NPT connections. Do not exceed the rated air inlet pressure, as overpressure can damage diaphragms and internal components.
