Product Description

Product Description

MH15 SERIES Gear Pump Overview

The Metaris MH15 is a high-performance, fixed-displacement external gear pump engineered for rugged hydraulic systems that demand extreme durability and field reliability. As a premium roller-bearing style pump, the MH15 is designed to be 100% interchangeable with industry standards like the Parker/Commercial P15 series. Its heavy-duty cast iron construction makes it an exceptional choice for demanding mobile equipment, material handling, and industrial applications where component longevity is non-negotiable.

Features and Benefits

Rugged Three-Piece Cast Iron Construction:
Unlike light-duty aluminum pumps, the MH15 is built with high-tensile cast iron bodies, flanges, and covers. This robust material provides superior resistance to mechanical fatigue and structural deflection under high-pressure conditions, ensuring stable performance in the most grueling work environments.
Advanced Roller Bearing Design:
The MH15 utilizes precision-engineered roller bearings rather than traditional bushings. This design significantly enhances the pump's tolerance to fluid contamination and allows it to handle higher radial shaft loads, resulting in a longer service life and reduced maintenance intervals in harsh-duty cycles.
Pressure-Balanced Thrust Plates:
To maximize efficiency, the MH15 incorporates high-strength, pressure-balanced thrust plates. This technology automatically optimizes internal clearances between the gear faces and the plates, maintaining high volumetric and mechanical efficiency (often exceeding 90%) even at elevated operating temperatures.
High-Strength Alloy Steel Gears:
Featuring precision-machined, high-alloy steel gears and large-diameter journals, the MH15 minimizes bearing surface loads and friction. This precision engineering reduces heat generation and ensures smooth, consistent flow delivery under continuous operating pressures of up to 2,500 psi (172 bar).
Modular Versatility and Easy Integration:
The MH15 series offers a broad range of displacements (from 8.1 to 32.4 cc/rev) and supports a wide variety of mounting options, including SAE "A" and rectangular flanges. With multiple shaft configurations (splined, keyed, or tapered) and the ability to be assembled into multi-stage "tandem" pumps, it provides unmatched flexibility for both OEM integration and aftermarket replacement.

Applications

The Metaris MH15 series provides a rugged, field-proven power solution tailored for heavy-duty applications where component durability and resistance to harsh environments are the top priorities:

Heavy Mobile Equipment: A primary choice for truck-mounted cranes, utility service vehicles, and snow and ice control equipment, where the robust cast iron body withstands extreme mechanical stress and external environmental factors.
Rugged Agricultural Machinery: Optimized for demanding farm implements, feed grinders, and specialized harvesting equipment that operate in high-dust and high-vibration conditions where high-strength roller bearings are essential for longevity.
Material Handling & Lifting: Widely used in professional-grade forklifts, truck tail-lifts, and large scissor lifts that require reliable hydraulic power and high shock-load resistance during intensive loading cycles.
Waste & Refuse Management: Ideal for small-to-medium refuse collectors and recycling balers, providing the structural rigidity needed for high-frequency compaction cycles and continuous hydraulic flow.
Industrial & Forestry Support: Frequently employed in log loaders, wood processing machinery, and industrial power units for metal forming, offering a durable and easily serviceable solution that minimizes downtime in remote or high-intensity work sites.

Packaging & Delivery

MH15 pumps are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.

MH15 Gear Pump FAQ

1. What are MH15 series gear pumps

The MH15 is a high-performance, fixed-displacement external gear pump characterized by its rugged roller bearing design and heavy-duty cast iron construction. Engineered as a 100% interchangeable alternative to the Parker/Commercial P15 series, it is a "workhorse" pump designed for high-stress hydraulic systems where field reliability and structural integrity are more important than weight savings.

2. What makes the MH15 different from standard aluminum gear pumps

The MH15 is built for extreme environments where standard aluminum pumps might fail:

Full Cast Iron Construction: Unlike aluminum pumps (like the Marzocchi ALP or GHP series), the MH15’s body, flange, and cover are all made of high-tensile cast iron, offering maximum resistance to mechanical fatigue and external impact.
Roller Bearings vs. Bushings: Instead of friction-based bushings, the MH15 uses precision roller bearings. This allows the pump to better handle fluid contamination and higher radial shaft loads, extending the service life in harsh mobile applications.
Serviceability: Its three-piece modular design makes it easy to repair or reconfigure (such as changing rotation or stacking into tandem units) in the field.

3. What is the working pressure range of MH15 pumps

The MH15 is designed for steady, high-torque power delivery. Depending on the gear width/displacement, the series typically handles:

Continuous Pressure: Up to 2,500 PSI (172 bar).
Intermittent/Peak Pressure: Up to 2,750 PSI (190 bar).
While its peak pressure is lower than some hybrid aluminum pumps, its ability to maintain these pressures under heavy shock loads and high-duty cycles is industry-leading.

4. Can MH15 pumps replace other brands

Yes, the MH15 is one of the most versatile replacement pumps on the market. It is a direct "drop-in" for:

Parker/Commercial Intertec: P15 Series.
Permco: P1500 Series.
Muncie: PJ Series.
To ensure a match, confirm the Mounting Flange (typically SAE A 2-bolt), Shaft Type (9-tooth spline or 5/8" keyed), and Gear Width (which determines the displacement).

5. What hydraulic oil is suitable for MH15 gear pumps

To protect the high-strength steel gears and roller bearings, the following is recommended:

Oil Type: Premium mineral-based hydraulic fluids with high Anti-Wear (AW) additives.
Viscosity: Standard ISO VG32 to VG68. The pump performs best within a viscosity range of 100 to 150 SUS (20 to 30 cSt), but can handle cold starts up to 2000 SUS (430 cSt).
Filtration: Due to the precision roller bearings, maintaining oil cleanliness is critical. A minimum filtration of ISO 4406 19/17/14 (or better) is recommended to prevent debris from damaging the bearing races.

6. What is the typical speed range of MH15 pumps

The MH15 is optimized for mid-to-high speed operation, typically ranging from 600 RPM to 2,400 RPM. Its robust internal design allows it to be driven by truck PTOs or industrial electric motors, delivering consistent flow even when the system experiences sudden load changes.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
