Mechanical and hydraulic grout pumps vary widely in power, complexity, capacity, and price. Selecting the most cost-effective product for the masonry contractor's needs requires thorough research of factors such as economics, application, and use frequency. Also consider pressure capabilities, aggregate sizes, power sources, and replacement parts availability.
