  Mechanical driven diaphragm pumps type UGD

The dosing pumps type UGD are studied to offer a high reliability and a metering precision also after a long working period.
The simple construction permits the maintenance operations to unexperienced personnel.
The pumps UGD are manufactured according to the Standards 89/392 CE and following modifications.

The pump casing on which is installed the gear is made of die-cast aluminium and it is in monobloc execution, as well as the lantern of the pump head and the lantern of the motor.
The pumping head can be supplied in 316 S.S. or in PVC.
The diaphragm is made of rubber with inserted fabrics and externally lined with PTFE.

Working principle
The dosing pumps type UGD are mechanical diaphragm type connected to the driving mechanism through a shaft. The system is type spring return.
The profile of the membrane is designed to assure a flow variation directly proportioned to the stroke.
The electric motor drives the diaphragm through a gear type worm and worm wheel installed in the pump casing. The wheel is installed on the side of the driving shaft that pushes the rod connected to the diaphragm through a cam.
The return of the plunger is assured by the releasing of the spring installed on the rod that is compressed during the pushing phase.
The gear is oil lubricated and it is supported at the ends by overdesigned ball bearings.
The flowrate can be adjusted manually or automatically with elctric or pneumatic strike positionners.
The adjusting system is based on a regulation micrometric screw with a rod that shuts the plunger stroke.
This system assures the dosing accuracy and the repeatibility.
The dosing range varies from 0 to 100% of the flowrate.

Electric motors
The electric motors are manufactured according to the Standards UNEL-MEC.
The main characteristics are: frame B14, eurovoltage, 3 phases, multyfrequency, mechanical protection IP 55 and insulation Cl F.
On request it is possible to install single phase motors.
