PTO Pumps

HM 250, 350, 500

The compact design of the HM, along with its capacity and durability makes it an ideal pump for a mini-pumper, wildland vehicle or tanker and will take up only a minimum amount of the payload space on your chassis. The space and weight saved enables you to carry a larger booster tank with better weight distribution. While intended as a booster pump, the HM also serves equally well when pumping from a hydrant or drafting.

You can depend on it for discharging effective pressure streams through 1 1/2" and 2 1/2" hose. If you are considering replacing an old, worn-out pump on an apparatus, the HM is ideal for retrofitting, in fact we recommend the HM pump wherever there might be a tight and difficult installation. The HM Assembly #3 pump comes as a complete assembly (with or without relief valve) for immediate midship installation. The three basic models let you add only the performance features you need. All HM configurations offer the convenience of pump-and-roll operation.
