WP116 is a modern self-priming water pump with a hydraulic motor. The pump is designed for the suction of water that has accidentally entered the collecting siphons in the lower parts of gas networks. Water can enter gas pipes after cracks or maintenance interventions, this mass of water that has accumulated in the lower part of the network can fill the siphons and also overflow, clogging the pipes and preventing the normal free passage of gas. Water can enter and damage the gas meters and cause other problems well known to gas maintenance crews. WP116 is made of non-sparking bronze and with moving parts without metal/metal contacts, so there is no possibility of creating localised overheating points. The hydraulic function (no current!) means implicit safety, which must be guaranteed in this delicate operation. For use, it is sufficient to connect the suction mouth of the pump to the siphon with a flexible hose and then vent and pump out the water/gas/air mixture, all in complete safety and with the gas line in normal operating condition. The extracted liquid must be disposed of in accordance with local regulations, as it is hazardous waste. WP116 is unique in its kind, because features, function and safety should not be missing in the equipment of modern gas maintenance teams.Practical, robust and safe, it is irreplaceable in useMade from "non-sparking" anti-explosive bronzeLarge water filter prevents dirt and metal shavings from entering the pumpThe water filter can be opened in a few seconds for cleaning and inspectionRequires minimal and simple maintenanceTechnical data:Water flow rate: 110 L/min at 1 metre head25 L/min at 20 metres headDelivery head: max. 20 metres (2 bar)Suction height: max. 6 metres above the water levelHose connection: Ø40mm (suction and pressure line)Ideal suction diameter: 25 mmWater quality: filtered waterHydraulics: 20-30 l/min at 100-210 bar
