The RONO high pressure plunger pump is a triplex plunger pump and is used to convey various edible fat products through multi-purpose process lines. The pump cylinder is separated into three chambers in which the plungers are moving to gently transfer the product. The suction and discharge side of each plunger are equipped with special dimensioned pump valves to ensure the highest volumetric efficiency. All safety related control elements, e.g. the stainless steel pressure relief valve, the pressure transmitter with switch and the oil pressure safety switch, are of course included. The pump is designed to always maintain a stable operation.
