XD Cast Iron Gear Pump

The XD Series Cast Iron Gear Pump is specifically
designed for high flow applications demanding peak
performance and long life in extreme operating
conditions.

Displacement:

34 to 90cc (2.04 – 5.40 cir)

Pressure:

Rated - 276 bar (4000 psi)

Peak - 303 bar (4400 psi)

Temperature:

Continuous - 104°C (220°F)

Intermittent - 115°C (239°F)

The XD pump utilizes many of the rugged design
features of the D Series product line, including
durable cast iron construction, advanced pressure
plate design, Viton seals and high capacity journal
bearings.

Typical applications for the XD include: mining,
construction, agriculture, material handling, forestry,
the marine industry, transportation and the
petroleum industry.

The XD Cast Iron Gear Pump is ideal for mobile
equipment applications with aggressive duty cycles,
severe temperatures and demanding performance
requirements.

Features

•

High strength, cast iron construction offers thermal stability, contamination resistance, and strength for consistent performance and
durability in severe duty cycle applications.

•

Advanced pressure-balanced load plates optimize volumetric efficiency across the range of operating speeds and pressures.

•

Heavy duty, low friction bearings provide long life in low viscosity, high pressure conditions.

•

Forward located bearings integrated into the front flange increase radial and axial load capacity, eliminating the need for a typical
bolt-on outrigger assembly.
