Dayton 3HJW2 Double Diaphragm Pump Kynar Santoprene 49 GPM

SKU CH-D7S1-30DE5

Air-operated double-diaphragm pump moves 49 GPM with Kynar housing and Santoprene diaphragms for chemical resistance

  • Air-driven design eliminates electric-motor maintenance
  • 49 GPM maximum flow handles high-volume transfer
  • Kynar housing resists aggressive chemicals
  • Santoprene diaphragms withstand 212 °F fluid temperature
  • 100 psi operating pressure suits demanding industrial tasks

Double Diaphragm Pump for Industrial Fluids

This Dayton air-operated double diaphragm pump handles industrial fluid transfer with a maximum flow of 49 GPM. The Kynar housing and Santoprene diaphragms resist chemical attack at temperatures up to 212 Degrees F. It suits plants needing reliable, seal-less pumping for aggressive liquids.

Suited for Chemical Transfer.

The pump fits processes that require gentle, pulse-tolerant flow and solid passage up to 3/16 in. It is not for buyers who need hydraulic pressure above 100 psi or continuous metering accuracy better than ball-check valves provide. Operations needing electric drive or submersible installation should look elsewhere.

Simple Air Connection, Watch for Contaminated Supply

Installation connects a 3/8 in FNPT air line and 1 in NPT fluid ports on a single manifold. The main issue is dirty or unlubricated compressed air causing valve stiction or premature diaphragm wear. Clean, regulated air supply prevents most field failures.

Questions about this item

What air supply pressure and volume do I need to run the 49 GPM pump?

The pump is rated for a maximum operating pressure of 100 psi; size your compressor and regulator to deliver that pressure at the required CFM for 49 gpm flow.

Can I keep my existing 1 inch NPT piping when installing this pump?

Yes, the pump has 1 inch NPT inlet and outlet connections that match standard 1 inch NPT pipe threads.

How can I verify the pump is delivering its rated flow after installation?

Measure the discharge volume over a timed interval; at full supply pressure it should approach 49 gpm with the 3/16 inch maximum solids passing freely.
