 For many jobs requiring single pours of less than 50 cubic yards, contractors can profitably use 

small-line pumps. The smaller pumps are also a practical alternative for larger pours with slow

 placing rates. WHAT IS A SMALL-LINE PUMP? Small-line pumps can be divided into two general 

categories--pea-rock and 1-inch-minus pumps. Pea-rock pumps are trailer-mounted ball-valve 

machines designed to pump plaster, grout, or concrete that usually contains about 70% sand and 

30% 1/2-inch-minus coarse aggregate. Trailer-mounted or truck-mounted 1-inch-minus pumps (also 

called 3/4-inch rock pumps) usually have a swing tube, S-tube, or rock valve instead of a ball valve.

 The 1-inch-minus pumps have features similar to larger trailer pumps and are designed to pump 

structural concrete for floors on ground, elevated decks, columns, and other structural members. 

WHY USE A SMALL-LINE PUMP? Pea-rock pumps are ideally suited for residential applications. 

They're small enough to be towed by a pickup truck and used without blocking or overloading streets. 

For commercial work, 1-inch-minus pumps are often the most practical machines to use when the 

pour rate is determined by how fast the concrete can be placed or finished. GETTING THE MOST 

OUT OF YOUR PUMP INVESTMENT Contractors who buy their pumps also need to invest in 

operator training and a regular maintenance program. Concrete pumps require more frequent 

inspections and service than most types of construction equipment.
