Power Plant Industry
Electric actuators make up a small part of a power plant – perhaps only two or three per cent by capital cost – but they play a vital role. A large power plant uses hundreds of valves to manage flows of water and steam. Valves may be used to stop and start flow, reduce or increase flow, control the direction of flow, regulate a flow or process pressure or relieve a pipe system of a certain pressure. Applications include pollution control, feed water, cooling water, chemical treatment and steam turbine control systems.
Water Treatment Industry
Peristaltic pumps solve many of the challenges associated with treating wastewater. They can accurately dose the chemicals used to treat water such as sodium hypochlorite, lime and caustic sodas. Due to the fact that the fluid is completely enclosed within the pump’s hose, resistance to chemical corrosion and physical abrasion can be overcome with chemical/abrasion resistant hoses. No other pump component comes into contact with the fluid and therefore abrasion on the pump’s rotating parts is non-existent.
Oil and Gas Industry
In the oil, gas and petrochemical industry, precision control of the flow of product through valves in the system is vital, and modulation of that flow depends on the valve actuator. These critical pieces of equipment must perform reliably and safely under the most extreme conditions: very high and low temperatures, drought or high-rainfall environments, remote situations in deserts or the arctic, and the corrosive effects of chemicals, high humidity or salinity for extended periods. In potentially explosive atmospheres, explosion protection is required; and in some applications, fireproof operation is critical.
Chemical medium transportation is a big problem in the chemical industry. Albin peristaltic hose pumps are capable of pumping many different chemicals, including:
l Sodium hypochlorite l Sodium hydroxide
l Calcium hydroxide l Cyanide solutions
l Plating solution l Catalytic agents
l Sulphuric acid l Solvents and resins
