Gorman Rupp T3A60S-B Pump
Spare Parts for T3A60S-B Self Priming Pump
Product Summary
The Gorman-Rupp Super T Series T3A60S-B is a high-capacity self-priming centrifugal pump designed for heavy-duty applications requiring superior solids-handling capability combined with reliable performance in demanding industrial and municipal environments. Built with the same proven design as the T3A3S-B series but optimized for higher flow rates, this pump delivers exceptional service in wastewater bypass, construction dewatering, mining operations, and industrial process applications.
- High-Capacity Solids Handling: Passes up to 2.5-inch diameter spherical solids through 3-inch suction and 1.5-inch BSP discharge connections, ideal for sewage, slurries, and debris-laden liquids in municipal and industrial applications
- Proven Self-Priming Performance: Achieves up to 6-meter suction lift with fast, reliable priming and repriming capability, eliminating need for costly foot valves and enabling flexible above-ground installation
- Rugged Industrial Construction: Heavy-duty cast iron construction with optional stainless steel components, hardened wear surfaces, field-replaceable wear plate, and integrated pressure relief valve for operator safety
- Minimal Downtime Maintenance: Back cover removal provides complete access to all wearing parts without disconnecting piping, enabling rapid inspection, adjustment, and component replacement in the field
- Versatile Drive Configurations: Available with electric motor (single or three-phase), diesel/petrol engine, or bare shaft for custom drive arrangements with flexible coupling or V-belt options

Troubleshooting, Common Faults & Solutions
Pump Fails to Prime
Likely Cause: Strainer clogged, suction lift too high, leaking seal or gasket, collapsed suction hose lining, or air leak in suction line
Action / Part: Clean strainer, verify suction lift within 6m maximum, check pump vacuum (should pull 20" Hg or more), replace leaking seal (46513-150) or gaskets (10959G, S1748), replace collapsed suction hose, seal all suction line connections with pipe dope
Pump Stops or Fails to Deliver Rated Flow/Pressure
Likely Cause: Air leak in suction, worn seal/gasket, insufficient liquid in casing, contaminated check valve, plugged air release valve, clogged impeller, discharge head too low, or worn impeller/wear plate
Action / Part: Seal suction leaks, replace seal (46513-150) or gaskets, refill pump casing through fill cover (priming), clean/replace check valve assembly (46411-060), clear air release valve/piping, remove impeller debris, adjust discharge valve, check impeller-to-wear plate clearance (.010-.020"), replace worn impeller (11406) and/or wear plate assembly (11407A)
Pump Requires Too Much Power
Likely Cause: Pump speed too high, discharge head too low, liquid too thick
Action / Part: Check driver output speed, verify sheaves/couplings correctly sized, adjust discharge valve to increase head, dilute liquid if possible, open discharge valve fully and run at maximum governed speed
Pump Clogs Frequently
Likely Cause: Strainer clogged, check valve binding, suction lift too high, impeller clogged/damaged, pump speed too slow, or suction intake not properly submerged
Action / Part: Clean strainer regularly, clean check valve (46411-060), verify suction lift within 6m, clear impeller debris or replace if damaged (11406), check driver output for proper speed, verify belts/couplings not slipping, ensure suction intake submerged per manual Figure 2 specifications
Excessive Noise / Cavitation
Likely Cause: Cavitation (air in liquid, blocked foot valve/strainer, restriction in line, excessive suction lift), pump not securely mounted, or pumping entrained air
Action / Part: Reduce suction lift and friction losses, clean foot valve/strainer, record vacuum/pressure gauge readings (consult factory if needed), secure all mounting hardware, eliminate air bubble source, verify proper suction pipe submergence
Bearings Run Too Hot
Likely Cause: Low/incorrect lubricant, drive misaligned, pump speed too high, bearing frozen, or piping not properly supported
Action / Part: Note: Bearings normally run to 160°F (71°C). Check SAE No. 30 non-detergent oil level via sight gauge (14A) - maintain at middle of gauge, align drive properly (see manual Section B), reduce power source speed, check/replace bearings (S1749, 23252-013) if frozen, support suction/discharge lines independently
Seal Leakage
Likely Cause: Worn/damaged cartridge seal, insufficient seal cavity lubrication, or contaminated seal faces
Action / Part: Replace complete cartridge seal assembly (46513-150) - never reuse old seal, fill seal cavity with SAE No. 30 non-detergent oil to middle of sight gauge (14), verify seal plate gasket (10959G) not leaking, check O-rings (S1748) for damage
Pump Overheats / Pressure Relief Valve Activates
Likely Cause: Operating against closed discharge valve, insufficient flow, liquid temperature exceeds 160°F (71°C), or pump running dry
Action / Part: CRITICAL: Stop pump immediately if overheated - allow complete cooling before servicing. Never remove covers/plugs from hot pump. Open discharge valve, verify sufficient flow, cool liquid if over 160°F, refill pump casing if run dry (priming), replace pressure relief valve (26662-005) after any overheating event
Incorrect Rotation (Three-Phase Motors)
Likely Cause: Three-phase wiring incorrect
Action / Part: CRITICAL: Correct rotation is counterclockwise when facing impeller. Running pump in reverse will cause impeller to unscrew from shaft, causing severe damage. Disconnect pump from motor before checking rotation. Have qualified electrician interchange any two of three phase wires to change direction
