Abstract: A vehicle, such as a truck, includes mixing and pumping equipment for mixing a liquid and a particulate material (e.g., cement) and for pumping the mixture. One application is to pump the mixture into a wellbore for cementing a casing or liner to the wellbore inner wall. The vehicle includes a cab, with the mixing and pumping equipment positioned behind the cab. The equipment includes one or more reservoirs, with at least one used as both a mixing and displacement tank. A hose assembly is also positioned on the vehicle. To reduce the weight load placed on the rear axle(s) of the vehicle, relatively heavy components, such as the pump, are placed further forward on the truck. In one arrangement, the pump may be placed between the cab and the one or more reservoirs.
