PN Series Decompressors - Technical Data Summary
▪ Application: Primarily for agricultural use (tanker outfitting), also suitable for industrial applications (lorry outfitting).
▪ Technology: Rotary vane pump. The rotor rotates eccentrically; centrifugal force keeps the vanes against the pump body, with an oil film providing sealing and lubrication.
▪ Lubrication & Materials: Forced lubrication via gear pump and adjustable oilers. Copper shaped pipes; aluminum intake/exhaust conveyors.
▪ Built-in oil tank on all models (PN 106 optionally available with side oil tank and automatic lubrication system).
▪ Cooling: Air-cooled via natural airflow over outer fins on the high-strength cast iron body.
▪ Valves: Integrated check valve. Standard 4-way manifold; optional 5-way Mixer-type diverter valve for mixing tank liquid during distribution.
»IV. Sewage suction truck hydraulic system:
♦ Hydraulic Control System: Multi-way manifold with lever controls for precise tank lifting and rear door regulation.
♦ Tank & Door Actuation: Robust hydraulic cylinders for 45° tank lifting and rear door opening, featuring a neutral "median" lever position.
♦ Electrical & Monitoring Interface: Weatherproof cabinet with centralized controls (Power, Warning/Boom/Rear Lights, Knife Gate Valve), Emergency Stop, and Low Water Level indicator.
♦ Pressure Regulation: Precision pressure gauges and manual valves for safe monitoring and adjustment.
♦ In-Cab Convenience Controls: Ergonomic cab panel for directional (Left/Right) and music/warning switches.
