REB/DB-Tender(E)-16/2025-26

The proposed hydraulic actuation power-generation module shall constitute a structurally integrated, high-pressure electrohydro dynamic power pack architecture, fabricated as a consolidated skid-mounted assembly engineered for sustained cyclic duty in precision-controlled industrial environments. The system shall incorporate a 7.5 HP, IP55-rated, S1 duty, three-phase squirrel-cage induction motor (Siemens/BBL/CG class) imparting rotational torque through a dynamically balanced bell housing- coupler interface to a radial-piston, fixed-displacement hydrostatic pump calibrated for a volumetric throughput of 3.7 LPM under continuous steady-state conditions. The hydraulic reservoir subsystem shall comprise a 100-litre, thermally-stabilised, low-turbulence fluid containment vessel mounted on a reinforced trolley framework and equipped with a multi-stage contamination-control suite including a high- efficiency suction strainer, filler-cum-breather module, analog oil-level indication assembly, and return-line filtration element (Hydroline standard), ensuring ISO-grade cleanliness compliance, Without Oil The fluid power distribution topology shall be consolidated within a precision-machined hydraulic manifold block (Hydropack grade), integrating a manual mechanical directional control valve, high-response pressure relief valve, pilot-operated check valve, dual in-line unidirectional check valves, and an auxiliary hand-pump cartridge module (Poly/Prism specification) to facilitate emergency and non-electric hydraulic actuation functionality. System sensory and diagnostic instrumentation shall include a 4-inch glycerine-damped bourdon-tube pressure transducer (0-400 kg/cm2 range) of Kains/Wika lineage, interfaced through a high-isolation pressure gauge isolator (Hyloc) to mitigate pulsation and overpressure shock loading. The fully integrated power unit shall be structurally and functionally rated for maximum operational working pressure of 700 kg/cm2, ensuring resilience against extreme transient hydraulic impulses, fatigue stress mechanisms, and long- duration high-pressure duty cycles, conforming to relevant electrohydraulic and industrial mechanical design standards.
