QUIETER OPERATION. COMPETITIVE PRICING. CLASS 10 GEARS. NEW. FEATURES and BENEFITS. NEW. MODULAR DESIGN bearings and gears are self-contained within the housings. Input and output adaptors are not required to retain the bearings. Input and output adaptors can be added or changed anytime prior to unit installation. SOS SPUR GEARS (solid-on-shaft) one-piece gear/shaft design provides consistent and uniform alignment. Reduces the total number of parts. Bearings pressed on gears simplify assembly. SIMPLER TO SERVICE does not require pressing shafts into bearings and gears through the housings. Ball bearings do not require shimming or special adjustment of pump pads and input adapters. FEWER PARTS adapter groups are reduced to a single set of input housings and output pads for the entire product line.

2 Gears (31 total) are interchangeable across different models. WET SPLINE oil passages built into the housings, along with the bearing design, create constant oil flow across splines and through bearings, resulting in longer, trouble-free operation. DROP-IN REPLACEMENT footprint is interchangeable with present pump drives and with the competition. HIGHER RATING gear geometry and large ball bearings result in a higher horsepower rating over the present product line. QUIETER OPERATION AGMA class10 gears provide smoother operation. COMPETITIVE PRICING due to economy of scale; commonality of parts results in higher volume of fewer parts. Gear and housing designs result in less assembly time. SHORT LEAD TIME large inventory range held in Australia allows quick turn around of orders. HYDRAULIC PUMP DRIVES RATINGS. Durst has developed a family of gear drive products for The power ratings in this brochure are based upon the following use with hydraulic pumps and motors.

3 These drives are operating conditions: available for mounting SAE standard hydraulic flanges Continuous SERVICE (8 hours/day). and pump or motor shaft configurations directly to the Uniform operating loads. gear drive unit. Models are available to mount directly to Maximum oil sump temperature of 93 C (200 F). SAE flywheel housings, with or without clutches or can be driven through independent mounting arrangements. Ratings are based upon component life using a 1:1 ratio @ 2500. rpm for a 2000 hour L-10 life. The full unit rating can be loaded THERMAL CAPACITY through one pump pad provided the total loading does not exceed The thermal capacity is defined as the power a gear drive unit rating. Durst pump drives are engineered for an optimum will transmit continuously without overheating. Durst pump balance between mechanical and thermal capacities. Durst drives drives are used in such a wide variety of operating are designed to accept 100 percent starting overloads or momentary conditions that only mechanical ratings are shown.

5 OPTIONAL LUBE PUMP AND OIL COOLER. REDUCED PUMP SPLINE WEAR. Most models can be supplied with a centrally mounted All Durst models now feature a new lubrication system where the gear pump for passing lube oil to a water or air cooled lubricant is directed through the centre of the gear to the gear shafts heat exchanger. We stock heat exchanger kits for most across the pump spline intersections. This feature ensures that models. premature spline wear caused by fretting will not occur. OIL OUT BACK TO.
