Jungheinrich 50312811 Water Pump for DFG/TFG 40-50 Forklifts

Overview

The 50312811 Pump, Water is a replacement cooling-system component for Jungheinrich forklifts, including the CD/CL 40-50 C/H, DFG/TFG 40-50, CK/CS and TFG 40 series. As the heart of the engine’s cooling circuit, the water pump circulates coolant between the engine block and the radiator, keeping operating temperatures stable during long shifts and heavy loads. A failing pump typically shows up as coolant leaks, overheating or bearing noise, and continued operation can lead to serious engine damage. Fitting a new 50312811 Pump, Water restores reliable cooling and helps protect your truck’s engine.

Compatibility

This Jungheinrich water pump, part number 50312811, fits the following model series:

• Jungheinrich CD/CL 40-50 C/H series
• Jungheinrich DFG/TFG 40-50 series (diesel and LPG counterbalance trucks)
• Jungheinrich CK/CS series
• Jungheinrich TFG 40 series

Whether you need the 50312811 for CD/CL trucks or a matching pump for a DFG/TFG 40-50, always confirm the part number against your truck’s data plate or parts manual before ordering. Closely related models can share bodywork but use different cooling components, so verifying the number is the surest way to guarantee a correct fit.

Quality and Reliability

The 50312811 water pump is manufactured to match the dimensions, mounting points and performance characteristics of the original Jungheinrich unit. A precision-cast housing, an efficient impeller and a durable shaft and seal assembly are engineered to handle continuous coolant flow and thermal cycling in demanding materials-handling environments. The pump installs as a direct replacement, with no modification to the cooling system required.

Installation and Maintenance Tips

Keep these points in mind when replacing the pump:

• Verify that part number 50312811 matches your forklift’s identification plate or parts book before ordering.
• Drain the coolant into a suitable container and dispose of it in line with local regulations.
• While the system is open, inspect hoses, the thermostat and the drive belt, and replace any worn parts at the same time.
• Clean the mounting surface, fit a new gasket where required and tighten the fasteners evenly to the specified torque.
• Refill with the coolant grade recommended by Jungheinrich and bleed the system thoroughly to remove air pockets.
• Run the engine, check for leaks around the pump housing and re-check the coolant level after the first operating cycles.

Cooling-system work should be carried out by a trained technician with the truck safely immobilised and the engine cold.
