SDB & TP Series Gear Pump | SDB36.36F9H1-R687, SDB40.27R172M, P20350C | High Pressure Hydraulic Pump

SDB & TP Series Heavy-Duty Tandem High-Pressure Gear Pumps

Product Overview: The SDB and TP Series represent a premium line of tandem high-pressure gear pumps engineered specifically for heavy-duty construction vehicles and mobile hydraulics. This featured selection includes flagship models such as SDB36.36F9H1-R687, SDB40.27R172M, P20350C, and TP20400. As the primary power source for dump truck hoists, waste compactor mechanisms, and hydraulic lifting equipment, these series utilize rugged cast-iron bodies and precision axial pressure compensation. This ensures elite volumetric efficiency even under frequent reversal and shock loads. Its tandem design allows a single drive shaft to power two independent circuits, significantly optimizing system space and costs.

Key Technical Advantages:

• Heavy-Duty Durability: Constructed with high-strength cast iron housings for superior fatigue resistance, built to withstand extreme instantaneous pressure ripples found in mining and construction sites.

• Efficient Tandem Output: Supports dual-circuit oil supply, meeting the flow demands of different actuators (such as lift cylinders and auxiliary motors) simultaneously.

• Excellent Self-Priming: Specially designed suction passages ensure rapid self-priming in low-temperature or high-viscosity fluid environments, preventing dry-run damage.

• Long-Life Sealing System: Equipped with high-temperature and high-pressure seals to effectively prevent shaft leakage and extend service intervals.

• Precise Fitment Options: Various flanges (e.g., F9H1) and shaft suffixes (e.g., R172M) are available to ensure 100% “Plug-and-Play” replacement for original equipment.
