Power plants require a variety of chemicals throughout the facility to enable or optimize processes. Cooling and boiler water treatment is one of the most critical areas because a failure will directly affect power generation. Proper chemical treatment assures maximum uptime of cooling towers and boilers thus reducing operational costs and assuring the process is optimized. LIGAO metering pumps and packages are highly reliable with a proven track record of effective chemical delivery and consistent performance.

LIGAO rotary lobe pumps are designed for low, medium and high-viscosity media and offer gentle pumping action and reliable performance. With its robust construction, each pump can be equipped with different types of rotors to meet high standards of quality and reliability. Collectively, they provide operating economy and high flexibility of use. LIGAO rotary lobe pumps been widely and successfully applied in following food industries: Chocolate, baking products, sauce, liquid dairy products, cheese, yogurt, ice cream, wine making, beverage, sugar, cooking oil, and so on.

Petrochemicals are the feedstock for polymers, solvents, detergents, adhesives, plastics, lubricants, and other materials. Chemical plants produce this feedstock by fluid catalytic cracking of petroleum fractures. This processing requires numerous chemicals such as corrosion inhibitors, emulsion breakers, oxygen scavengers, and many more. LIGAO offers metering pumps and packages that ensure accuracy in delivery of critical or difficult fluids. Our pumps can be designed according to API675 with steady-state accuracy of ±1% . In addition, the efficient, reliable designs of our pumps and packages require minimal maintenance lowering maintenance costs over the pump life cycle.

The chemical industry is focused on the synthesis of finished or intermediate products. In chemical processing, the toxic nature of fluids, combined with numerous temperature and pressure variations during production requires metering pumps, packages, and mixing technology that is safe, adaptable and highly-reliable. LIGAO offers standard and customized metering pumps and packages with hydraulically-actuated or plunger piston type metering pumps to deliver ±1% steady-state accuracy. We can handle a variety of chemicals . Flexible multiplex configurations enable our pumps and systems to address a wide range of capacities and pressures right for your process requirements.

Wastewater must be treated efficiently, cost-effectively and within the appropriate quality standards. LIGAO metering pumps can offer accurate chemical dosing with long service life, which can minimize maintenance cost. Our wide range of metering pumps can inject chemicals such as coagulants, disinfectants, softening agents, acids and bases for pH control, de-chlorination chemicals, and many more. Design features such as durable construction and five layers composite PTFE diaphragm lead to it can withstand varying fluid, temperature, and environmental conditions while capacity adjustment enables accurate output flow control. Our pumps are well-known for their reliability. With preventative maintenance, these metering pumps perform at peak levels, leading to less shutdowns and long-term cost benefits.
