Control volume pump

Chemicals are used in numerous processes of industries such as Petrochemical & refinery, textile, chemical, automotive, and ceramics industries. Our package units for chemical preparation and dosing, all components of which are manufactured out of materials carefully selected to endure the chemicals to be prepared, provide uninterrupted and problem-free operation.
While automated units are preferred in applications where high consumptions take place, semi-automated or even manual models can be used depending on the type of operation.

Features
•    Black anodizing Aluminum casing
•    Simple and robust spring return mechanical diaphragm pump
•    Uses mechanically actuated diaphragm to combine the characteristics of a plunger pump (linear flow rate) with the sealing advantages of a diaphragm pump
•    Suitable for batching operation
•    Minimum maintenance required
•    ATEX STD compliance (94/9/CE), group II category 3 (zone 2/22)
•    Single and multiple arrangements
•    Low cost, due to reduced number of components
 Processes
Disinfection, coagulation, flocculation, Boiler feed water, cooling and process water treatment, raw water purification, chemicals for ion-exchangers, supplementary water treatment and effluent water neutralization. Dosing of ammonia, hydrazine, phosphates in high-pressure areas (boiler feed water), lubricant dosing, corrosion inhibition, antiscalants, additives & catalysts, odor control, dosing of flammable liquids.
 Applications

•    Oil, Gas, Petrochemical industry

The heart of the liquid end in a plunger metering pump is a highly resistant piston made from coated stainless steel. As soon as the plunger is moved into the dosing head, the suction valve closes and the feed chemical flows out of the dosing head through a discharge valve. When the plunger moves in the opposite direction, the discharge valve closes due to the negative pressure in the dosing head. Fresh feed chemical flows through the suction valve into the dosing head.
Plunger metering pumps can be found in oil and gas production (onshore/offshore), refineries, the chemical and petrochemical industry, the pharmaceutical, cosmetic and food production industries, and as bottling pumps in the packaging industry.
