Cast Iron Gear Pump

 

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

D-Pump

20% smaller than conventional gear products, our 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 the D-series of pumps, a wide array of applications rely on the D-pumps.

Cascade Group 3

Turolla Cascade

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

Dolomites Group 3

Turolla Cascade

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 as previously mentioned 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.
