The VersaPump 2 can be used for either slabjacking or concrete pumping. A smaller design can allow the pump to be near the jobsite, whether it be concrete raising or shotcreting. A 25-hp engine provides 150 to 750 psi and can pump up to 3?8-in. pea-gravel concrete at 10 cu. yd./hr. The pump can be operated by one person and includes a remote control for pumping action at the nozzle regardless of the working conditions. Hydraulic Mudpumps. 800-626-2464.
