Coxreels HP1125-4-325-AB Compressed Air #6 Gast Motor Rewind Hose Reel | HP1125 Series | 1/2" Hose Diameter | 325' Hose Length | 5000 Max PSI | Less Hose

Production-grade high-pressure installations that run the maximum 325-foot reach of the HP1125 Series at 5,000 PSI and retract that drum automatically through a full shift of cycles need both the pressure rating and the motor durability to match. The Coxreels HP1125-4-325-AB pairs the #6 Gast cast iron 6-vane compressed air motor (a heavier-duty motor construction than the aluminum 4-vane #4 Gast, with six vanes for smoother torque delivery under the sustained startup load of a fully loaded 325-foot drum and a cast iron body that dissipates the heat generated by high-cycle retraction more effectively than aluminum at this drum scale) with direct gear drive (no chain gears engage the drum directly for quiet, smooth retraction without chain stretch or lubrication intervals) on the HP1125 Series high-pressure frame electroless nickel plated steel 90° NPT swivel rated for 5,000 PSI, AFLAS seals, CNC-spun ribbed discs, permanently lubricated pillow block bearings, and all-welded 12-gauge steel A-frame. The motor's air supply circuit and the hose's 5,000 PSI working fluid path are completely separate the #6 Gast draws from a dedicated small-diameter shop air line at standard supply pressure, while the working fluid travels exclusively through the drum hose, outlet riser, and swivel. For high-pressure test facilities, large oilfield service stations, industrial fluid delivery systems, and water jetting operations where the reel retracts under a full 5,000 PSI-capable drum load repeatedly throughout the production day, the HP1125-4-325-AB is the motor and frame combination built for that duty.

• 325-foot maximum capacity the longest single-drum reach in the HP1125 Series; cast iron motor construction provides the durability margin the maximum-load HP1125 Series drum demands in production-frequency retraction environments
• Electroless nickel plated steel 90° full-flow NPT swivel inlet hardened for 5,000 PSI service; greater pressure capability and corrosion resistance than the brass swivel on standard 1125 Series models
• AFLAS swivel seals fluoroelastomer compound with superior chemical and heat resistance over Nitrile; rated to 250°F and suited to hydraulic fluid, petroleum, chemical injection, and high-pressure process service
• Exclusive low-profile outlet riser and open drum slot design provides a non-crimping, flat smooth hose wrap across all 325 feet of drum capacity
• Heavy-duty CNC robotically spun and ribbed discs with rolled edges for greater strength, durability, hose protection, and operator safety
• Sturdy one-piece, all CNC robotically welded 12-gauge steel A-frame base not bolted for superior reel structure; mounting pattern in base for wall, ceiling, or overhead installation
• Permanently lubricated, self-aligning pillow block bearings for trouble-free, smooth drum rotation under full production-cycle retraction frequency at maximum drum capacity
• Adjustable tension brake prevents free-wheeling during hose deployment; long-lasting chip-resistant, rust-inhibiting CPC powder coat finish; 2-year manufacturer's limited warranty

Applications

• High-cycle hydraulic test facilities production test benches running repeated 5,000 PSI pressure cycles where the reel retracts between every test and the cast iron motor body handles the sustained thermal load of high-frequency retraction on the maximum-capacity drum
• Large oilfield & well service production stations permanent reel stations at high-volume service operations where 5,000 PSI chemical injection and stimulation fluid lines span 325 feet and the reel cycles repeatedly throughout the production shift
• Industrial high-pressure fluid delivery high cycle hydraulic fluid supply and elevated-pressure process fluid delivery across large plant floors where retraction frequency and 5,000 PSI service pressure both demand the cast iron motor construction over aluminum alternatives
• High-pressure water jetting production operations commercial and industrial jetting operations at above 3,000 PSI where the reel retracts multiple times per shift and 325 feet of reach covers the largest surface preparation and cleaning areas from a single fixed station
• Plant maintenance & MRO high-pressure, high-cycle, maximum reach large industrial facility overhead reel stations where 5,000 PSI service lines, 325-foot reach, shop air availability, and production-level retraction frequency all apply simultaneously

FAQs

Q: What makes the cast iron #6 Gast motor specifically suited to the 325-foot HP1125 drum in high-cycle use?
A: Three factors converge at the 325-foot HP1125 drum that make cast iron motor construction more valuable than on smaller drums. First, the drum load: a fully loaded 325-foot drum of 1/2-inch hose is the heaviest retraction load in the HP1125 Series, generating more startup heat in the motor on every cycle. Second, the frequency: in high-cycle production use, the motor starts against that heavy load repeatedly throughout the shift. Third, the pressure: at 5,000 PSI working pressure, this is the most demanding configuration in the HP1125 line. Cast iron dissipates heat more effectively than aluminum under sustained cycling, and the six-vane design delivers more consistent torque through the full retraction stroke. The aluminum #4 Gast handles this drum at moderate frequency; the cast iron #6 Gast is built to handle it at production frequency.

Q: What is the difference between the HP1125-4-325-AB and the HP1125-4-325-EA at maximum capacity?
A: Both provide high-output automatic retraction on the maximum-capacity 325-foot HP1125 Series drum at 5,000 PSI, but the power source differs. The -AB uses the #6 Gast cast iron air motor drawing from your existing shop air supply no electrical wiring to the motor required. The -EA uses a 115V AC, 1/2 HP explosion-proof reversible AC-rectified motor drawing from a 115V AC circuit no shop air supply to the motor required, and it carries a classified hazardous location rating. Choose the -AB when shop air is available at the mount point and the installation area is not a classified hazardous location; choose the -EA when 115V AC power is available and either an explosion-proof rating is required or no compressed air supply is present at the reel.

Q: What air supply does the #6 Gast motor need to retract the 325-foot HP1125 drum?
A: The motor uses existing shop air (typically 90 120 PSI) through a dedicated small-diameter air line independent of the 5,000 PSI working fluid path through the drum hose. On the 325-foot drum, the startup load is at its greatest in the HP1125 Series. Confirm your compressed air system can deliver stable pressure under maximum drum load while simultaneously supplying connected production equipment. Gast does not publish a universal CFM figure for this motor in reel retraction service.

Q: What is the difference between the HP1125-4-325-AB and the standard 1125-4-325-AB?
A: Both use the #6 Gast cast iron 6-vane air motor on the same basic chassis with direct gear drive. The difference is working pressure and swivel specification. The HP1125-4-325-AB is rated to 5,000 PSI with an electroless nickel plated steel swivel and AFLAS seals. The standard 1125-4-325-AB is rated to 3,000 PSI with a machined brass swivel and Nitrile seals. For applications at or below 3,000 PSI, the standard 1125-4-325-AB is the more economical choice; for applications requiring up to 5,000 PSI, the HP1125-4-325-AB is required.

Q: Does the reel come with hose included?
A: No the HP1125-4-325-AB ships less hose. The drum accepts 1/2" ID / 7/8" OD hose up to 325 feet. Coxreels recommends SAE 100R16 wire braid hose for HP1125 Series reels rated for hydraulic and high-pressure oil service at up to 5,000 PSI and 250°F. Use assemblies with fittings rated and crimped for high-pressure service, and verify hose OD does not exceed 7/8 inch to ensure correct drum wrap across the full 325-foot capacity.
