PTO Dump Pump Hydraulic Hydro Cylinder C102 – Direct Mount

The C102 model delivers robust pumping capacity with a CCW air shift design, optimized for direct mounting on dump trucks. It features a 7/8″ 13-tooth spline shaft and an integrated air shifter cylinder for simplified installation. The design supports up to higher RPM requirements, making it suitable for demanding dumping sequences. Construction includes heavy-duty roller bearings, pressure-balanced thrust plates, and high-pressure shaft seals to maintain performance under load. Batch testing for relief valve accuracy and flow ensures reliable operation across shifts and weather conditions.
PTO Dump Pump Hydraulic Gear Pump C Series 49 GPM

This C Series gear pump provides a direct mount option with a left-hand rotation design. It delivers 49 GPM at 1800 RPM, which supports rapid dump cycles and efficient hydraulic performance. The 13-tooth 7/8″ spline input shaft aligns with common PTO configurations, while the direct-mount integration reduces installation time and potential misalignment. Its design emphasizes consistent flow and solid sealing to reduce leaks in high-pressure dump operations. A reliable choice for operators seeking a straightforward, high-flow solution.
Hydraulic PTO Dump Pump G101 Bi-Directional Gear Pump

The G101 is a bi-directional gear pump designed for flexible dump truck operations. It provides 15 GPM at 1000 RPM with a 1″ keyed input shaft and remote mounting capability, enabling installation in tighter or uniquely configured hydraulic bays. The remote mounting design supports adaptable routing of hoses and plumbing, while the bi-directional flow allows for versatile dump and lift cycle controls. This pump prioritizes reliability and ease of maintenance in shared-use fleet environments.
Bestauto Hydraulic Pump 21.2GPM For Dump Applications

Bestauto’s 21.2GPM hydraulic pump emphasizes strong flow with a maximum speed of 540 RPM and a high operating pressure of 2500 PSI. It uses a standard SAE 12 outlet and SAE 16 inlet configuration, which helps ensure a tight fit with common hydraulic lines and modules. The cast iron casing with a power-coated finish enhances resistance to impact, corrosion, and rock-solid performance under heavy loads. This model is well-suited for dump trailer use and other heavy-lift scenarios where consistent, high-flow output is critical.
RYFT Hydraulic PTO Pump 21.2 GPM 540 RPM

RYFT’s pump features 21.2 GPM at 540 RPM with a 7.4 GPM high flow rate and a standard SAE 16 inlet / SAE 12 outlet arrangement. The 6-tooth SAE 16 inlet and SAE 12 outlet provide compatibility with common truck hydraulics, while the sturdy iron housing with a power-coated finish enhances durability for outdoor, heavy-use environments. The design focuses on reliable starts and smooth operation across dump cycles, making it a practical option for fleet maintenance and upgrades.
Buying Guide
- Flow rate and speed: Higher GPM at appropriate RPM improves dump cycle speed but requires a compatible reservoir and valve system. Choose a pump that matches your truck’s cylinder size and desired lift speed.
- Pressure rating: Ensure the pump can sustain the peak system pressure your dump setup demands. Exceeding pressure ratings can cause seals to fail and accelerate wear.
- Mounting compatibility: Direct-mount pumps reduce alignment issues and simplify installation. Check shaft size, rotation (clockwise vs. counterclockwise), and whether remote or integrated shift components are needed.
- Shift mechanism: Some pumps include integrated or pre-mounted air or cable shift systems. Consider ease of installation, maintenance accessibility, and compatibility with your current control valves.
- Durability: Look for robust housings (cast iron or aluminum), quality bearings, seals, and thermal relief features. Batch testing for valve relief and flow can indicate reliability across temperatures and loads.
- Port sizing: Ensure inlet/outlet port sizes (SAE 12, SAE 16, etc.) align with your hoses and fittings to minimize adapters and leaks.
- Compatibility with OEMs: If replacing an existing pump, verify that your chosen model replaces the same Parker, Permco, Muncie, or equivalent series to maintain performance and warranty alignment.
- Maintenance access: Consider how easy it is to service seals, bearings, and relief valves. Pumps with modular components can reduce downtime during fleet maintenance.
- Reliability in 24/7 environments: For frequent dump operations, prioritize pumps with proven durability, sealed-shaft designs, and materials suited to harsh weather and dust exposure.
- Warranty and support: Check manufacturer warranty terms and available technical support to minimize risk when upgrading or retrofitting.
