Factory&FAQ

DE1R 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.
Rugged Cast Iron Housing: Unlike aluminum pumps that can suffer from deflection or "body stretching" at high pressures, the DE1R’s cast iron frame maintains tight internal clearances and extends service life under high-pressure duty cycles.
Pressure-Balanced Bushing & Wear Plate Design: It uses advanced pressure-balanced components that provide superior bearing surfaces and axial compensation, offering greater resistance to thermal shock, fluid contamination, and wear than typical aluminum-body pumps.
High Power-to-Weight Ratio: Despite its robust construction, the DE1R delivers exceptional power density in a compact footprint, making it ideal for space-constrained installations.
The DE1R is a compact high-pressure specialist. Depending on the specific displacement, the series typically handles:
Continuous Pressure: Up to 4,000 PSI (276 bar) for displacements ≤ 32 cc/rev; up to 3,500 PSI (241 bar) for larger displacements.
Intermittent/Peak Pressure: Up to 4,400 PSI (303 bar) for displacements ≤ 32 cc/rev; up to 3,840 PSI (265 bar) for larger displacements.
This robust pressure rating makes the DE1R ideal for driving high-force lifting, compaction, and auxiliary systems on professional-grade utility and construction vehicles.
Yes, the DE1R is a high-quality alternative to other premium compact cast iron pumps. It is often used as a replacement or upgrade for:
Parker/Commercial Intertech: P30, P31, and P50 Series
Eaton/Vickers: 20, 25, and 35 Series
Metaris: MH315 and MH325 Series
Permco: P1900, P2100, and P2500 Series
To ensure a successful swap, verify the Mounting Flange (SAE A or B), Shaft Type (9 or 13-tooth spline, or keyed), and Displacement (cc/rev) to match your existing system.
To protect the precision bushings, wear plates, and hardened steel gears, the following is recommended:
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 100 to 150 SUS (20 to 30 cSt), though it can handle cold starts up to 2,000 SUS (430 cSt).
Filtration: Cleanliness is vital for bushing and wear plate lubrication. A minimum filtration of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging internal components.
The DE1R series is designed for a wide operating speed range:
Continuous Speed Range: 600 to 3,400 RPM (max 3,400 RPM for displacements ≤ 25 cc/rev; 3,000 RPM for larger displacements).
Minimum Recommended Speed: 600 RPM, to ensure adequate lubrication and prevent cavitation.
Note: Operating above the recommended maximum speed may shorten service life and reduce efficiency, while operating below the minimum can cause insufficient lubrication and noise.

DE1R pumps are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
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.
