Factory&FAQ
SGP2 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 deflect under high pressure, the SGP2’s cast iron body maintains tight internal clearances, reducing wear and extending service life in heavy-duty cycles.
Pressure-Balanced Bushing Design: It uses advanced pressure-balanced bushings that distribute loads evenly, offering superior resistance to fluid contamination and thermal shock compared to standard roller-bearing pumps.
High-Pressure Efficiency: With axial compensation technology, the SGP2 automatically adjusts clearances to minimize internal leakage, maintaining high volumetric efficiency even at maximum operating pressures.
The SGP2 is a high-pressure compact gear pump. Depending on the specific model, the series typically handles:
Continuous Pressure: Up to 24.5 MPa (245 bar / 3,550 PSI).
Intermittent/Peak Pressure: Up to 29.4 MPa (294 bar / 4,265 PSI).
This robust pressure rating makes the SGP2 ideal for powering high-force actuators and complex hydraulic circuits in construction and material handling equipment.
Yes, the SGP2 is a high-quality alternative to other premium gear pumps. It is often used as a replacement or upgrade for:
Shimadzu SGP1 Series (as a higher-performance successor).
Nachi IPH Series external gear pumps.
Parker PGP Series gear pumps.
To ensure a successful swap, verify the Mounting Flange (SAE A or B), Shaft Type, Displacement (cc/rev), and Port Configuration to match your existing system.
To protect the precision bushings and hardened steel gears, the following is recommended:
Oil Type: Premium mineral-based hydraulic fluids with strong Anti-Wear (AW) and anti-oxidation additive packages.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 20 to 100 cSt, though it can handle cold starts down to 10 cSt.
Filtration: Cleanliness is critical for long bushing life. A minimum filtration level of ISO 4406 18/16/13 is recommended to prevent abrasive particles from damaging the internal components.
The SGP2 series operates within a wide speed range to suit various applications:
Minimum Speed: 400 rpm (for stable flow at low pressure).
Maximum Continuous Speed: 3,000 rpm (depending on displacement and fluid viscosity).
Operating within this range ensures optimal lubrication, prevents cavitation, and maintains high efficiency.

SGP2 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.
