The continuous dosage of additives and adjuvants in oenology process equipments and, more specifically, at the exit of the crushed grapes collection hopper and immediately before the progressive cavity pump (dosage of sulfur dioxide, enzymes, ascorbic acid, jellies, bentonites, ecc …) allows a perfect mixing of the product and its dispersion in the must during the whole manufacturing process. The peristaltic dosing pump has to have salient features such as: adjustable flow-rate, waterproof box, 24, 110 and 230 Volt supply - according to the final markets -, vertical suction height 2 m, head pressure not more than 0.5 Bar, good resistance to acids and to disinfectants, affordable price. The peristaltic pumps range IPCR is able to match the following characteristics: . the flow speed is adjustable by means of an easy potentiometer placed on the front of the pump . the peristaltic dosing pump has a plastic case IP55 with an easy rear mounting bracket . the peristaltic pump can accept whatever supply voltage from 20 up to 260 Volt, either AC or DC. This means a great versatility in the power definition (low voltage at 24 V – USA voltage at 110 V – European voltage at 230 V). . the pump is perfectly self-priming up to a height of 2 meters . 0.5 Bar head pressure . the peristaltic pump offers an absolute competitive price The tubes for peristaltic pumps of the range Teknoprene TPV (SANTOPRENE/MARPRENE/NORPRENE) are highly compatible with this application.
