A graphic that shows the different between a two-line system and a three-line system with hose running to and from the reservoir and through the pump. Muncie Power Products' line of dump pumps is available in a three-line system option to help prevent the most common dump pump failure of high temperatures resulting from the pump being operated too long in neutral.

A three-line system includes a separate line to return hydraulic oil from the cylinder directly to the reservoir instead of forcing its way back through the inlet line. The three-line allows faster down cycles and ultimately runs cooler.

Available dump pumps include the E Series and S Series. Both the E Series and S Series are available in the three-line option. Two-line systems are also available. These systems can function effectively, but only if not left operating too long in neutral.

The E Series has a maximum pressure of 2,500 PSI and is the standard equipment for tandem, tri-axle dumps, and dump trailers with high-volume cylinders. Its pressure-balanced wear plates promote high efficiency. Larger port options for fast cycle times are available with the EH model.

Designed for small single or tandem axle dump trucks, the S Series is available in 6, 11, and 15 GPM at 1,000 RPM sizes. The three-way dump pump valve allows for proper single-acting hoist operation on smaller dump truck applications.
