Main Components and Construction<\/h3>\n

The Borelli Universal Support for Group 4 Pumps – 25609 Series is built around a robust housing (code 25009.1), which serves as the protective and load-bearing enclosure for the entire power transmission system. Smooth rotation of the 42 mm diameter shaft is ensured by a high-strength bearing assembly, specifically a 3212 A bearing (code 503212\/2) and a 16012 A bearing (code 501601). To preserve the integrity of the hydraulic system and protect the internal components against contaminants, the assembly incorporates two 60x75x8 shaft seals (code 306075), supported by a dedicated gasket (code 30470.2).<\/p>\n

Power Transmission Specifications and Operating Loads<\/h3>\n

Torque transmission is handled by a shaft engineered according to the strict DIN 5482 standard, featuring an A 48×44 spline profile. For secure mechanical fastening, the assembly uses a 12x8x60 key compliant with UNI 6604 (code 421286). In terms of structural strength, the pump support is designed to withstand substantial radial and axial stresses, operating reliably under loads of 150 daN and 520 daN, with a maximum operating load of 694 daN.<\/p>\n

Maintenance and Hydraulic Connections<\/h3>\n

The support assembly incorporates design features that facilitate periodic maintenance operations. It includes a grease nipple compliant with UNI 7663-A, featuring an M8x1.25 thread (code 500000.1), for lubricating the internal moving components, together with an oil drain plug with a 1\/8″ G connection (code 940182). The flange (code 30470) is securely fastened to the main housing using six M10x25 socket head cap screws (code 611025).<\/p>\n

Compatibility and Dimensions of Available Flanges<\/h3>\n

The Borelli Universal Support for Group 4 Pumps – 25609 Series offers excellent compatibility with various industrial flange mounting standards. The main housing features centering diameters of 145 mm and 165 mm, with M12 threaded holes (15 mm deep) and M10 threaded holes (30 mm deep). Available flange options include the Universal 4 P flange (code 30403, center-to-center distances of 114.3 mm and 149.5 mm), Universal 3.5 P flange (code 30402) and Universal 3 P flange (code 30401). SAE B 2-bolt and 4-bolt configurations (codes 30421 and 30422, 101.6 mm dimension) and SAE C 2-bolt and 4-bolt configurations (codes 30431 and 30432, 127 mm dimension) are also supported. For European coupling applications, the system accommodates Linde Guldner PF 75 flanges (code 30463), PF 20-35-50 flanges (codes 30461 and 30462), and the Bosch ZG3 flange (code 30417, with center-to-center distances of 160 mm and 105 mm).<\/p>\n
