Part Number: HM250

The HM pump has been a top seller for Darley and the industry for many years due to its compact design, capacity, durability, and simplicity in maintenance. The HM is an ideal pump for tanker applications, brush trucks, and mini pumpers and provides excellent pump and roll performance. The compact design also allows it to fit into tight spots in retrofits of existing apparatus. The HM pump is available in three different assembly levels, from the pump only to a fully manifolded offering to meet all needs.
