Durst Introduces Compact Two-Pump Drive
May 23, 2012—Durst has announced the latest technical innovation in the company's next-generation line of hydraulic pump drives. The model 2PD05 further expands the broad portfolio of Durst modular pump drives to include a two-pad design with 10-inch pump centers and 5-inch gear centers. Durst engineered the 2PD05 specifically for mobile off-highway applications requiring a compact footprint, lighter weight and versatile mounting configuration.
The model 2PD05 further expands the broad portfolio of Durst modular pump drives to include a two-pad design with 10-inch pump centers and 5-inch gear centers.
The new pump drive affords a cost-effective drive solution including but not limited to construction, mining, forestry, agriculture, rail maintenance and oil field equipment. Weighing approximately 200 pounds, the 2PD05 measures 8 inches deep x 11 inches high x 21 inches wide. The 2PD05 meets SAE and AGMA standards and is compatible with SAE pump shafts up to a 13 tooth - 8/16 spline (SAE D). It can be used as a drop-in replacement for Funk's 28000 series pump drives. The simple, one-piece modular format allows for easier assembly and installation.
The 2PD05 has a maximum torque rating of 700 lb-ft. The pump drive is rated for a maximum input power of 370 horsepower. It offers a choice of gear ratios from 1:1 to 2:1. One of the most important benefits of the 2PD05 is its flexible mounting options. The pump drive can be mounted horizontally or vertically to overcome space constraints and restrictive limitations in equipment design.
Long life and reliable performance are hallmarks of Durst's modular pump drive line. The 2PD05 runs cooler and is simpler to service. The class 10 spur gears run on heavy-duty ball bearings. Bearings and gears are self-contained within the housings. Durst's patented casting design keeps oil constantly flowing through the bearings and provides for wet spline operation, even at startup, thereby preventing fretting corrosion.
Pump pads and input adapters can be easily changed without disturbing bearings. Because of the single seal, bearing, gear and adapter group design, there are fewer parts to inventory.
"The 2PD05 adds depth and breadth to Durst's product offerings," said John Locarno, global sales and marketing manager. "We leveraged our strength in heavy-duty pump drive applications to develop a system that is ideal for applications up to 370 horsepower. Introducing this new drive moves us closer to our goal of becoming the single source for all our customers' pump drive needs."
