Pump Installation Specifications

  • Mounting Interface: Standard SAE and European 4-bolt mounting flanges designed for secure, precise alignment on pump drives and power take-offs.

  • Drive Connection: Keyed parallel shaft and tapered shaft configurations engineered to accept flexible couplings with minimal radial load.

  • Port Orientation: Side-ported configuration with threaded or SAE split-flange connections to prevent leakage under peak pressure.

  • Alignment Tolerance: Maximum coaxial misalignment between the pump shaft and drive shaft kept within 0.05 mm to prevent premature bearing and seal wear.
