Delta Power DM Series Motors

DM Series hydraulic motors are designed with performance in mind, including: High-strength cast iron bodies with precision machined filling and trapping grooves, and hardened alloy gears and shafts to run smoothly, special Buna-N o-ring and shaft seals to withstand up to 200 PSI return line back pressure, antifriction bearings for 60-70% starting torque, ball thrust bearings to withstand thrust and radial shaft loads, and integral check valves to permit bi-directional rotation (to eliminate the need for external case drains). And, they will turn as slow as 300 rpm…or lower on low-torque applications. DM Series motors are found in material handling equipment, agricultural implements, snow removal equipment, marine gear and numerous industrial equipment and machine tools…as drives for pumps, fans, compressors, mowers and other applications where moderate starting torque and moderate to high speed efficiency is needed. And, because of their design and manufacturing quality, they can be expected to add to the overall performance and life expectancy of the equipment.
Installation Notes: Hydraulic motor controls should be placed on the pressure side of the motor in order to preclude high seal or case pressures. Return line should be straight to tank. On DM1 thru DM8 series, be especially careful since these units require that the mounting bolts are installed to complete the assembly. The two shipping bolts are not sufficient to make the assembly intact.
