Darby Equipment Company
6-20" Primus Pipe Bending Machine (HPBP6-20)


FEATURES AND TECHNICAL SPECIFICATIONS

Features/Advantages:
pipe roller cradles The HPBP6-20 has a 31.5 gal (119 L) fuel tank and a 91 gal (344 L) hydraulic
tank with 82 gal (310 L) fill capacity. The large hydraulic tank helps keep
the oil cooler, extending the life of the hydraulic system.
pipe roller cradles Commercial Intertech four-section hydraulic control valve provides
bending operations and optional hydraulic mandrel operation.
pipe roller cradles Machine sideplates are reinforced with stiffeners for optimal frame life. Side plates are 3/4" (19.1 mm) T1 steel. All welds are preheated, heat controlled and made “in position.”
pipe roller cradles Frame cross tubes supporting the hydraulic cylinders have 3/8" (9.5 mm) wall thickness.
pipe roller cradles Parker Seal Lok™ hydraulic system prevents leaks and has a working pressure rating of 3,000 psi (206.8 bar).
pipe roller cradles Murphy control panel includes electric start, throttle control, oil pressure, tachometer and hour meter.
pipe roller cradles Hydraulic cylinders can be disassembled without cutting for ease of repair.
pipe roller cradles Pinup is fully reinforced to prevent spreading.
pipe roller cradles 325 Quincy air compressor is hydraulically driven by its own circuit.
pipe roller cradles 10-micron hydraulic return linekeeps oil clean to extend the life of the system.
pipe roller cradles Oil cooler in compressor drive circuit keeps the circuit cooled. It continuously circulates, even when the compressor is not running. This extends the life of the hydraulic system.
pipe roller cradles Inner pipe roller provides smooth pipe translation.
pipe roller cradles Darby-designed tracks utilize Berco components.

Performance:
pipe roller cradles Maximum bending force at front of stiffback is 301,600 lbs (136,803 kg).
pipe roller cradles Air compressor provides 240 psi (16.6 bar) for mandrel operation.
pipe roller cradles With engine running at 2,200 rpm, the hydraulic vane pump produces 46 GPM (174 LPM) at operating pressure.

Options:
pipe roller cradles Air-cooled Deutz Diesel Engine
pipe roller cradles Poly tracks
