TUROLLA CAST IRON GEAR PUMPS

Turolla has offered the rugged D-Series line of pumps for over 20 years. Every component of the D-Series is specifically designed for maximum efficiency, dependability, durability and reliability in performing continuous operation in heavy duty applications with severe duty cycles and temperature conditions, all within the industry leading package size and power density.

To provide gear solutions for group 3 frame sizes, Turolla has introduced the Cascade and Dolomites lines of cast iron products. Utilising a slightly larger frame size, the Cascade and Dolomites families extend the range at which Turolla offers cast iron units from 7.00cc’s all the way to 100.00cc’s.

Features & Benefits

  • Non-tin-coated external surface bearings, allowing higher bearing loads due to high pressures
  • Thrust plate design for high efficiency over a wide temperature range
  • Teflon® coated bushings for extended life under extreme temperature and pressure conditions
  • High strength cast iron construction for efficient performance in continuous operation
  • Custom engineered shaft bearings and dual pressure-balanced thrust plates for high starting torque and long life.

Features & Benefits (unique to D-Series)

  • Easy installation in optimised machines due to compact, power-dense design
  • Viton® seals are standard to sustain higher temperature and fluid capabilities
  • Variety of integrated valve options

Turolla offers a group 2.5 category D-series as well as a group 3 Cascade and Dolomites pump in cast iron construction. The general specifications of each is listed below.

D-Series

20% smaller than conventional gear products, Turolla cast iron gear pumps give great power density in a small package.  D-series pumps are known for their rugged, dependable performance under high pressure.

The broad range of shaft drives, integrated valves, and side or rear port options gives great flexibility in system design.  Coupled with the modularity and compact nature of these pumps, a wide array of applications rely on the D-series.

Cascade Group 3

Cascade pumps are a three piece cast iron design similar to the D-series products, but are scaled in size to be a true group 3 offering.  Shifting the performance range by increasing the frame size allows the Cascade to not only offer slightly high pressure ratings, but moves the corner power displacement well above maximum D-series displacements.

Cascade options allow for great flexibility by featuring mounting flange options from an SAE A 2-bolt, to SAE C 2 + 4 bolt.

Shaft options and auxiliary pad options also ensure a majority of mounting and drive requirements can be accommodated.  See the technical information literature for more details.

Dolomites Group 3

Dolomites pumps are a two piece “bucket” style cast iron design similar to the Cascade, but by combining the gear plate and rear cover reduces cost, complexity and potential leak paths.

The Dolomites pumps are only available in a single section configuration due to the two piece design, but have a slightly larger range of displacements and are generally less expensive than similar Cascade units.

Dolomites are a little less flexible with options versus Cascade, but SAE B mounting along with ISO, EU 4-bolt and UNI (Italian) mounting flanges are standard options.  Shaft options are slightly more limited, but standard group 3/SAE B options such as SAE B 13T, 20mm straight keyed, and 7/8” straight keyed are available.
