Description
Description
The Blackmer TXH Series is a cast iron sliding vane truck pump built for tank trucks and transports that handle clean, non-abrasive, non-corrosive fluids compatible with cast iron. The TXH3C uses horizontal parallel porting, which places the inlet and outlet on the same side of the pump and makes piping connections easier than on 90 degree ported truck pumps. It also installs on integral mounting feet rather than brackets.
A large diameter shaft turns on low friction, grease lubricated external ball bearings for smooth, quiet operation, and cartridge type mechanical seals keep pumpage away from the bearings while preventing external leakage. The double ended shaft lets the pump be driven from either side, in either direction of rotation. An adjustable internal relief valve is standard, with an optional piston air valve available for trucks running automatic pressure control systems.

Features and Benefits
- External roller ball bearings support the rotor from both sides, creating a stable environment for the internal mechanical seals
- Dual ended shaft simplifies installation and allows drive from either side
- Blackmer mechanical seal and ball bearing construction provide maximum reliability
- Internal mechanical seals allow extended dry run and continuous operation with non-lubricating liquids
- Symmetrical bearing support assures even loading and wear for long life
- Adjustable relief valve protects the pump against excessive pressures
- External ball bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
- T-type strainers are available to protect the pumping system from welding slag and foreign matter in pumps and tanks
- High volumetric efficiency and symmetrical bearing support mean less required horsepower than other positive displacement pumps, saving on both motor operation and electricity
- Vanes can be replaced without removing the pump from the truck
- Self-adjusting sliding vane design maintains flow rates as the vanes wear
- Excellent self-priming, dry run, high suction lift, and line-stripping capability
Applications
Transport delivery, fleet refueling, and bulk transfer of fuel oil, jet and aviation fuel, gasoline, biodiesel, ethanol and other alcohols, solvents, ester, ketone, naphtha, ether, amine, aromatics, terpene, glycol, and additives.
Standard Configuration
Every TXH3C on this page is built with:
- Duravane vanes (code 4)
- Double ended shaft, driven from either side, clockwise or counterclockwise (code 40)
- Blackmer single mechanical seal, iron / FKM / carbon / FKM (code C0)
- Fluorocarbon (FKM) O-rings (code 2)
Choose your relief valve and flange connection from the menus above. Everything else is available by phone, see the Configuration Options table below.
Relief Valve Options
| Code | Relief Valve | Description |
|---|---|---|
| 1 | Standard Relief Valve | Adjustable internal safety relief valve, standard on every TXH3C |
| 2 | Corrosion Resistant Relief Valve | Corrosion resistant internal relief valve for more aggressive service |
| 8 | Air-Operated Piston Relief Valve (FKM) | Works with commercially available flow sensing valves to reduce discharge line pressure under bypass conditions. Supplied with the 70 to 125 psi air-operated relief valve spring |
| 9 | Air-Operated Piston Relief Valve without Spring (FKM) | For systems that use pneumatic controls to set high and low pressure relief valve settings. Supplied without a spring |
The standard and corrosion resistant valves take a steel spring in a 51 to 75 psi, 76 to 110 psi, or 111 to 125 psi range at no additional cost. Call to specify your required pressure range.
Flange and Connection Options
| Code | Connection |
|---|---|
| N | NPT flanges, 3 inch (standard) |
| W | Weld flanges, 3 inch |
| C | Gasket and cap screws only, NPT |
| B | Gasket and cap screws only, weld |
| X | No flanges, cap screws, or gaskets |
