GEAR PUMPS
Dump Pumps
G101 / G102
Compact dump pump and valve assemblies.Compatible replacement configurations.
TWO MOUNTING ARCHITECTURES
Remote Mount
Remote-mounted architecture driven through a driveline.
1 in round keyed shaft
Two drive shafts support installation for either drive direction. Identify the driven shaft and verify port arrangement.
Remote mounting and driveline must match the installation.
Direct Mount
Direct-mounted architecture for compatible PTO interfaces.
SAE B 4-bolt • 13-tooth spline
CW or CCW rotation is selected through the ordered reference; do not assume one pump operates in both directions.
SAE B 4-bolt • 13-tooth spline / DIN 4-bolt • 8-tooth spline option
Compatible replacement configuration. Final supplied configuration is confirmed by complete pump reference and SUNY quotation.

Pump input speedC 2.5 in / G 2.0 in gear-width reference. Actual supplied configuration is confirmed by complete pump reference and quotation.
INTERFACES & ROTATION
1 in round keyed shaft. Two drive ends; identify the actual driven end and verify installation orientation.
SAE B 4-bolt • 13-tooth spline / DIN 4-bolt • 8-tooth spline option.
CW or CCW rotation depends on the ordered reference. Confirm the viewing direction and driven end with the complete code; do not interpret the image as permission to reverse rotation.
Ports vary with the complete reference. Verify connection type, size and layout before ordering. Dimension references apply to the catalog G102 CW SAE B configuration, excluding DIN.

HYDRAULIC CONFIGURATION
A hydraulic circuit choice, independent of 101 / 102 mounting architecture.
One cylinder line and one reservoir line. Oil recirculates internally in neutral. For intermittent operation.
One cylinder line and two reservoir lines. In neutral, oil circulates through the pump and returns to tank. For continuous or intermittent operation.
A three-line installation requires the correct inlet sleeve. Final line configuration and required components are confirmed with the complete pump reference.
TECHNICAL REFERENCE
Two-line / three-line
Confirm the required hydraulic layout and components with the complete pump reference. Review the installation conditions in the hydraulic reference.
CONTROL
The manufacturer describes cab actuation by cable, with control of the single-acting dump cycle.
An air cylinder actuates the valve. Manufacturer kit references vary by series and accessory scope.
Control method, actuator and any hoses or fittings are confirmed in the quotation. Manufacturer reference kits are not a SUNY standard packing list.
TECHNICAL REFERENCE
Specifications first. A concise reference sheet when you need it.

TECHNICAL REFERENCE
Two-line / three-line
G101: 2.0 in gear width / Remote Mount reference. G102: 2.0 in gear width / CW / SAE B reference. DIN configuration dimensions are not represented by the SAE B reference table.
These are manufacturer configuration references, not measured dimensions of the supplied product. Confirm installation dimensions with the complete reference.
29 GPM @ 1800 pump RPM. Manufacturer average production data: reservoir oil 120°F, viscosity 150 SUS at 100°F. Actual pump speed depends on the PTO ratio and drive arrangement.
Specifications-page displacement rounding is retained; performance tables use 3.94 in³/rev. These are reference values, not SUNY test results.
Reference specifications are based on current Parker C/G Series manufacturer documentation. Final supplied configuration is confirmed by the complete pump reference and quotation.
