The Stalker ISO Hydraulic Driven Series from MTP is designed to deliver reliable, cost-effective performance for water carts used in mobile dust suppression. Built in Perth, WA, these Australian-made pumps offer shorter lead times and the proven quality Stalker Pumps are known for.
Conventional water cart pumps often create delays through unavailable parts, alignment issues and the need for specialist servicing. The Stalker ISO Hydraulic Series solves these problems with a close-coupled design that removes coupling alignment altogether, reducing downtime and keeping your operations moving.
Each pump features an easy on/off SAE-mounted hydraulic motor, allowing quick change-outs on site without pulling trucks out of service. This improves water cart availability, saves time, and cuts workshop hours—critical advantages for mine sites and construction projects.
Available in a range of casing and impeller materials, including cast iron, stainless steel and zinc-free bronze, the series is built to handle demanding conditions while keeping maintenance simple and efficient.
The result is a dependable, practical water truck pump that supports smoother, more efficient dust suppression operations.
