Stopped pump volume regulation dosage pump.
  
 
 
 
PASCAL´s dosage plunger piston pumps provide a wide range of models enabling to select different volumes to meet all the usage needs.
These models are suitable for pumping and dosing at low, medium or high pressure. They enable to measure and pour all types of non-abrasive, inert and corrosive filtered liquids from one vase to another; acids, alkali, alcohols, disincrustants, greases, pastes, fuels, etc

Principal Functioning
Dosage is achieved through the reciprocating motion of the plunger piston, guided to avoid lateral pressures on the connecting rod.
The chamber volume (head-diaphragm) can be enlarged or reduced. A set of valves takes advantage of this difference in order to measure and pump the liquid to be dosed.
Diseño y construcción
Dosage is achieved through the reciprocating motion of the plunger piston, guided to avoid lateral pressures on the connecting rod. Stainless steel cylinder and packaging, PTFE packaging and joints, heated heads and valve sets, diaphragm heads (single or double, with or without failure indicator) hydraulically combined with plunger piston enabling the pumping of products which, due to their nature, should not be in contact with the atmosphere. Washing lantern packaging.
 
Caracteristicas
  1- In the DRPI model, the volume is regulated, with the pump running or stopped, modifying the rod travel controlled by an eccentricity changer allowing for high repetitive precision
  2- Volume regulation is adjusted from 0 a 15.000 l/h and the pressure to 1.000 kg/cm2
  3- In all models, the plunger pistons are hard chromium plated or ceramic plated
  4- Oil-bathed closed casing
  5- Direct engine semi-flexible coupling
