Power Transmission Guards
Industrial Transfer Pump and Motor Guard Covers
Used to shield rotating shafts, couplings, belts, and components in industrial pumping system.
Durable, corrosion-resistant covers protect pumps and motors from exposure, debris, and rotating-equipment hazards.
Industrial Transfer Pump and Motor Coupling Covers enclose the exposed coupling connecting a pump shaft to its motor shaft, the primary rotating hazard on a direct drive pump and motor assembly. Machine Guard & Cover Co. builds these as one piece covers for smaller couplings, installed as a single unit over the entire coupling, or two piece covers for slightly larger couplings that split for installation and service. For especially large couplings, a fabricated box style guard is available instead. Each cover is sized to the specific coupling dimensions on your equipment, with dozens of standard part numbers already on file and custom sizing available beyond that.
Key Features
- One piece design installs as a single unit over smaller couplings; two piece design splits for installation and service on slightly larger couplings
- Sized specifically to the coupling's height, diameter, length, and offset from the mounting centerline, using Machine Guard & Cover Co.'s sizing chart
- Dozens of standard stock part numbers already on file, covering a wide range of common coupling sizes
- Custom sizing available for couplings that fall outside the standard chart
- Fabricated box style guards available as a separate product line for especially large coupling guarding needs
- Rigid molded construction, consistent with Machine Guard & Cover Co.'s broader guard cover line
- Straightforward retrofit for direct drive pump and motor assemblies where the coupling is the primary exposed rotating hazard
- Available in imperial (inch) or metric (mm) sizing per the manufacturer's sizing chart

Assembly / What's Included
Each coupling cover ships as a single molded shell (1 piece models) or a two piece split shell (2 piece models), sized to your coupling's dimensions per Machine Guard & Cover Co.'s sizing chart. The pump, motor, coupling itself, and mounting structure are not included; this is guarding only. For couplings too large for the standard 1 or 2 piece line, Machine Guard & Cover Co. offers a separate Fabricated Box guard line; contact them to confirm which product fits your coupling size before ordering.
Configuration Options
- 1 piece cover: for smaller couplings, installs as a single unit
- 2 piece cover: for slightly larger couplings, splits for installation and service
- Fabricated Box: a separate product line for especially large couplings, outside the scope of this page
- Dozens of standard part numbers on file by height, diameter, length, height to center, and inside radius; examples range from 1CC3.5-3-2.9 (smallest standard size) up to 1CC171410 (largest standard size)
- Custom sizing available for non standard couplings; submit dimensions using the manufacturer's sizing chart
- Imperial (inch) or metric (mm) sizing available
Materials & Construction
- Rigid molded plastic shell; confirm exact material and thickness with Machine Guard & Cover Co. when requesting a quote
- One piece or split two piece construction depending on coupling size
Applicable Safety Standards
Standards to be confirmed by PowerSafe. See: Machine Guard & Cover Co., Coupling Covers product line; cross reference against OSHA 29 CFR 1910.219 (mechanical power transmission apparatus), section and page to be confirmed.
Cover Doesn't Fit the Coupling
Gaps around the coupling, cover doesn't seat, or won't close
- Recheck the coupling's height, diameter, length, height to center, and inside radius against Machine Guard's sizing chart before ordering a replacement
- Confirm whether a 1 piece or 2 piece cover was ordered; couplings near the upper end of the 1 piece size range may fit better with a 2 piece design
- For couplings that fall outside the standard chart, request a custom sized cover or check whether the Fabricated Box line is a better fit
- Verify the cover hasn't warped or been damaged in shipping or storage before installation
Two Piece Cover Doesn't Align at the Split Line
Halves don't meet cleanly, gap at the seam, or hardware won't align
- Confirm both halves are being installed in the correct orientation relative to the coupling
- Check that mounting hardware holes on both halves line up before final tightening
- Inspect the split edges for damage or warping that could prevent a clean seam
Cover Interferes with Coupling Access or Maintenance
Can't inspect or service the coupling without full cover removal
- Confirm the correct part number was selected for your coupling; a 2 piece design allows service access without full disassembly of surrounding equipment
- Always remove the cover fully for maintenance rather than working through gaps or partial removal
- Contact Machine Guard & Cover Co. if frequent access needs suggest a different configuration would work better
Material & Environmental Wear
Cracking, discoloration, or brittleness over time
- Inspect for UV exposure related brittleness if the cover is mounted outdoors or near direct sunlight for extended periods
- Replace any cover showing cracks or stress marks rather than continuing to use a compromised guard
- Confirm the correct material and thickness were specified for your environment when the cover was ordered
Other Exposed Points on the Assembly
Belt, fan, or other rotating components near the coupling remain exposed
- This cover guards the shaft coupling only; belts, fans, and other exposed rotating components on the pump or motor assembly need their own guarding
- On belt drive assemblies, pair this coupling cover with a separate belt guard
- Contact PowerSafe to confirm full guarding coverage for the rest of your pump and motor assembly
Preventive Maintenance
To keep these covers performing reliably:
- Inspect mounting hardware for looseness at regular intervals, especially on equipment subject to vibration
- Check the cover for cracks, warping, or seam gaps (on 2 piece models) periodically
- Confirm the cover remains correctly seated after any coupling alignment or maintenance work
- Replace any cracked, warped, or otherwise damaged cover promptly rather than reinstalling it
Fault Tracking & Continuous Improvement
- Log any cover replacement, fitment issue, or maintenance access problem, including the equipment location
- Look for recurring patterns, such as repeated seam gaps tied to a specific coupling's vibration levels
- Use this history to standardize on the correct part number for each coupling location across your facility
