High Slip Motors Reduce Loading on Beam Pumping Installations

Beam installations using high slip motors (20 to 30 per cent range) can reduce gear box torques some 30 to 40 per cent over beam installation using conventional 8 per cent slip motors. In addition, high slip motors can reduce peak polish rod loads 10 to 15 per cent. These load reductions can mean a saving in capital expenditures plus a reduction in operating costs.
