1.- GENERAL DESCRIPTION DOSTEC-50 dosing pumps are heavy duty, high precission, piston pumps for dosing liquid products. This series allows many injection possibilities depending on the head being chosen. The available heads are from 330 to 1000 l/h for the piston series, and from 207 to 870 l/h for the diaphragm series.
The original packing is prepared so that carriage and storing of the product do not cause any damage to the product, as long as this is done far from heat sources and in dry, ventilated spaces. Inside packing we include: - DOSTEC-50 dosing pump - Handbook - Oil (700cm )
4.- OPERATION The rotational motion of the motor is transmitted by the gear box that consists of two major components, the pinion (A) and the ring gear (B). The pinion and the ring gear are linked to an axis with an eccentric bearing (C) that pushes the shaft (D) which is threaded to the diaphragm or the piston (E).

DOSING FLOW Through the micrometic regulator ,we will adjust the dosing flow from 0 to 100% depending on the wished value. It is not advisable a regulation under 10%. In order to check the dosing flow: 1.- Prime the pump immersing the suction pipe in a graduated receptacle (A). 2.- Mark in the receptacle the liquid level.

MAINTENANCE Before any maintenance operation we will check: That the pump is stopped and disconnected from the electric supply. There is no pressure neither inside the head nor in the impulsion pipe. It is advisable to empty the head before opening it. The staff in charge of the maintenance will use the adequate protection means in order to manipulate the dosed liquid.
