Factory&FAQ
VG22 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.
Tandem Flow Versatility: It delivers two separate flow outputs from one unit, eliminating the need for multiple pumps and reducing installation space and cost.
Robust Cast Iron Body: Unlike aluminum-bodied pumps, its cast iron construction maintains tight internal clearances under high pressure, preventing deflection and extending service life.
Pressure-Balanced Design: Advanced wear plates automatically compensate for axial clearances, ensuring consistent efficiency even at varying pressures and temperatures.
The VG22 is a high-pressure workhorse. Depending on the specific displacement variant, the series typically handles:
Continuous Pressure: Up to 3,000 PSI (207 bar).
Intermittent/Peak Pressure: Up to 3,500 PSI (241 bar).
This robust rating makes it suitable for powering high-force actuators, compact presses, and heavy-duty mobile circuits.
Yes, the VG22 is a reliable, high-quality alternative to other premium tandem gear pumps. It is often used as a direct replacement or upgrade for:
Parker/Commercial Intertech equivalent tandem models.
Nachi IPH series pumps.
Rexroth GPP/GPX series pumps.
To ensure a successful swap, verify the Mounting Flange (SAE A/B), Shaft Type (spline key), and Displacement (both pump sections) to match your existing system.
To protect the precision gears and bearings, the following is recommended:
Oil Type: Premium mineral-based hydraulic fluids with Anti-Wear (AW) additives.
Viscosity: Standard ISO VG32 to VG68. The optimal operating range is 20 to 30 cSt, though it can handle cold starts down to 430 cSt.
Filtration: A minimum filtration level of ISO 4406 18/16/13 is required to prevent contamination damage to internal components.
The VG22 is engineered for a broad operating speed range:
Minimum Speed: 600 RPM (to maintain adequate internal lubrication).
Rated Speed: 1,500 to 2,500 RPM.
Maximum Speed: 3,000 RPM (intermittent, check model-specific ratings).
