Dosing and Transfering Pump

can be delivered as:

• single pump
• multiblock pump
• combination pump
• complete dosing and control systems and small dosing units.

All parts in contact with the liquid are selected according to the medium to be pumped. We can deliver dosing pumps with the following materials:

• PVC
• PE
• PTFE
• titanium
• steel with hard rubber lining
• corosion and acid resistant steels
• perbunan
• hypalon
• viton

The capacity of the pump is constant and infinitely adjustable. Regulation is done by changing the stroke and/or by changing number of stroke. For this purpose the pump is provided with a scale-hand adjusting knob or with control gear motor including hand-wheel. Electrical control by a servo motor or pneumatic control by a small air motor. D.C. motors with Tyristor - control units can be delivered to use alternating current mains.

The proportional control of dosing volume is carried out as a functionof the measured value on a contact flow meter: the pump gives a full stroke volume of flow for each water counting impulse. Fully automatic dosing dependent on a main flor meter: continuous dosing proportional to the measured flow of main flow meter.

Proportional dosing depending on analogue measuring values (current, voltage, resistance). Direct dosing control of the pump is made by the converting of an input value to a proportional impulse frequency. Electronically controlled systems can be delivered for automatic control of the pH-value. Dosing value is controlled by automatic comparison of measured value to the preadjusted rated value. Charge dosing with digital flow preselection: the pump is shut off automatically after arriving at preadjusted dosing value.

Dosing pumps, tanks and fittings mounted to a compact units (tanks in polyethylene or steel). Units complete with foot valve, hand- or electric-mixer and with all other accessories such as dosing point connection, overflow valve, ball valve. These systems are robust, reliable and ideal for continuous operation.

Are installed on the water / steam systems for dosing of Hydrazin to avoid corrosion by binding of oxygen. This kind of plant is gas tight and fulfils the safety regulations of the industrial control societies.
