TXH Sliding Vane Pumps

Blackmer^® TXH3C and TXH35A cast-iron rotary vane pumps, which are part of the Iron Line of sliding vane pumps, have been designed for use on tank trucks and transports that handle a wide range of clean, non-abrasive and non-corrosive fluids that are compatible with cast iron.

TXH3C pumps are designed with horizontal parallel porting that can offer installers easier piping connections than pumps with 90° ported pumps. TXH3C pumps are also installed using mounting feet rather than brackets. Other features of the TXH3C models are a large diameter shaft with low-friction, grease-lubricated ball bearings for smooth and quiet operation. Cartridge-type mechanical seals provide reliable service while preventing external leakage. The double-ended shaft allows for either clockwise or counter-clockwise rotation. Internal safety relief valves are standard with an optional piston air valve for trucks with automatic pressure-control systems also available.

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 on 2-, 2.5- and 3-in models simplifies installation
Blackmer mechanical seal and ball-bearing construction provide maximum reliability
Internal mechanical seals allow for 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 pump against excessive pressures
T-type strainers are available to protect pumping systems from damage caused by welding slag and foreign matter in pumps and tanks
High volumetric efficiency and symmetrical bearing support means less required horsepower than other PD pumps, meaning a cost savings on both motor operation and electricity
External ball-bearings are isolated from pumpage by mechanical seals to maximize bearing life and minimize contamination risk
Easy maintenance: vanes can be easily replaced -- without removing pump from truck
Advantages of sliding vane technology:
- Unique sliding-vane pump design self-adjusts for wear to maintain flow rates
- Excellent self-priming and dry-run capabilities
- Sliding vane design provides sustained performance and trouble-free operation
- High suction lift and line-stripping capabilities
- Low maintenance and low life-cycle costs
