Action Electric Drum Pump ACT-HDESS with upgraded Marathon 5KC39RN44GX 1 HP 115/208-230V 3450 RPM motor, 316 SS wet end, Teflon/Viton seal, 3/4″ FPT outlet, EPDM 1″-ID hose; max head 10.0 ft (water); viscosity guidance up to 2000 cPS for non-flammable compatible liquids

Condition: Used — in great shape, tested and working. Includes pump + motor assembly, 5-ft EPDM hose, manual, and original (distressed) box. No other deficiencies noted.

Overview

This listing is for an Action ACT-HDESS stainless electric drum pump that has been retrofitted with a Marathon Electric 5KC39RN44GX, 1 HP, 3450 RPM, single-phase, frame 56C motor. The wet end remains 316 stainless with Teflon impeller/auger and a Teflon mechanical seal with a Viton® O-ring isolating the motor from the liquid. The pump is self-priming and intended for clean, non-abrasive, non-flammable liquids compatible with 316 SS/Teflon/Viton.

About the performance numbers you noticed

• The paper manual you have lists Max Head = 10.0 ft (water) and Max Viscosity = 2000 cP. Your head figure matches the factory table (10.0 ft), while the viscosity value differs from the PDF, which shows 500 SSU for ACT-HDESS.
• The PDF manual explicitly states ACT-HDESS to 500 SSU (a kinematic/time unit). 500 SSU at SG≈1 is roughly ~110 cP, far lower than 2000 cP. The head row in the same table shows 10.0 ft max.
  Interpretation: your paper manual likely reports dynamic viscosity (cP), while the PDF uses SSU; they’re different units. If you’ll share your liquid’s temperature and specific gravity, I can pin the exact SSU↔cP conversion for your case.

Note: Upgrading to a higher-HP motor can improve available torque at the coupling but does not increase the pump’s hydraulic limits of head/viscosity established by the wet-end design. For reliable expectations, use 10.0 ft max head and the viscosity range validated for the wet end.

Features

• 316 stainless-steel outer column and inner shaft for corrosion resistance.
• Teflon impeller & auger, Teflon seal with Viton O-ring for broad chemical compatibility (non-flammables).
• Self-priming electric drum pump design with simple flush-and-store maintenance.
• 3/4″ FPT discharge; includes 5-ft EPDM hose (1″ I.D.).
• Safety: not for flammable or explosive fluids/atmospheres; follow NEC/OSHA; GFCI recommended.

Specifications (as configured)

Pump/Wet End (factory data for ACT-HDESS):

• Max Total Head (water): 10.0 ft; typical flows ~10 GPM @ 0 ft and ~5 GPM @ 5 ft (water, 72 °F).
• Viscosity guidance: included paper manual: up to 2000 cP; PDF manual: up to 500 SSU (≈110 cP @ SG≈1).
• Materials in contact: 316 SS column & shaft; Teflon impeller/auger/seal; Viton O-ring.
• Discharge connection: 3/4″ FPT; Hose: EPDM 5-ft, 1″ I.D.

Installed Motor (current unit):

• Marathon Electric 5KC39RN44GX, 1 HP, 3450 RPM, 1-phase, 115/208-230 V, Frame 56C, Code J (per nameplate details).
• Replaces the catalog Dayton 6K181C (1/3 HP) referenced in the factory parts list.

Electrical / Use

• Factory docs note units ship wired 115 V; ACT-HDESS can be rewired for 230 V; use proper grounding/GFCI. Motor supports 115 or 208-230 V per nameplate.

Applications

• Transfer from 55-gal drums and totes of compatible non-flammable chemicals: water treatment salts/acids/bases, plating baths, soap solutions, food-adjacent non-flammables (e.g., vinegar, citric), and general plant liquids (see list).
• Batch make-up and day-tank top-off where total dynamic head is ≤10 ft and viscosity within guidance.

Chemical Compatibility (selected, per chart)

Acetic, citric, boric, lactic, tannic, sulfurous acids; alum; Na/K carbonates, chlorides, sulfates; ferric/copper/zinc salts; soap solutions; water; beer; beet sugar liquids; tomato juice. Always verify exact concentration, temperature, and SG and avoid flammables.

Cross-Referenced Models

• Original spec motor: Dayton 6K181C (1/3 HP) — parts list reference for ACT-HDESS.
• ACT-16ESS (air/universal motor version) — different motor, higher listed head on chart, but lower viscosity (100 SSU); not directly comparable to your electric model.

Comparable Products

• Similar stainless drum pumps with 316 SS/Teflon/Viton wet ends and ~10–15 ft head class from other industrial brands (ensure non-flammable service and equal materials).
• If your duty fluid is truly near 2000 cP, we may consider progressing cavity or high-torque drum pumps designed for higher viscosities.

What This Unit Can Be Part Of

• Drum transfer/dispense skids with inline flow meters and valves.
• Chemical batching to low-elevation tanks.
• Maintenance carts for non-flammable CIP/cleaner top-offs.
  (Respect the 10-ft head limit and viscosity window for predictable flow.)

Included in This Sale

• ACT-HDESS pump with Marathon 5KC39RN44GX 1 HP motor (installed)
• 5-ft, 1″-ID EPDM discharge hose
• Manual and original box (distressed)

Not Included / Notes

• No additional nozzle/meter unless pictured; no spare augers/seals beyond what’s installed.
• If you need the original 6K181C wiring/parts details for reference, I can provide the relevant page numbers.
