LEWA triplex®
LEWA triplex®
Compact, rugged, reliable.
Whether in the oil and gas industry, the chemical industry, the food industry or the energy sector, the LEWA triplex diaphragm process pump has been used everywhere in high-pressure applications.
The pump features tried-and-tested, patented LEWA diaphragm technology, absolutely secure and reliable operation and the world’s most compact design for a process pump. It also has the advantages of a long service life, minimal life cycle costs and high energy efficiency.
It is available in six different sizes, this allows its use in a wide assortment of processes and applications and lets it fulfill a wide range of requirements.
Good reasons for a LEWA triplex®
The LEWA triplex is a hydraulically actuated diaphragm process pump with a compact design that offers numerous advantages in relation to comparable pumps during high-pressure processes.
Solid, compact design
The LEWA triplex features a solid, durable and long-lasting overall design resulting from a one-piece crankcase and double bearing crankshaft. The space-saving monoblock design makes the triplex the world’s most compact process pump. This also makes it ideal for applications and processes with little installation space, such as oil drilling platforms.
Low-pulsation flow rate
The triplex series features very smooth running and a low-pulsation flow rate. The even phasing of pistons (eccentric offset) makes this possible. This means there is usually no need to install pulsation dampers in the pipeline system.
Unique suction capacity
The unique suction capacity of the LEWA triplex diaphragm process pump distinguishes it from other pumps. With an absolute suction pressure of up to 0.1 bar, it provides more than just a wide array of safe installation options. The operating costs for the entire system can also be decreased compared to other pumps.
Absolutely safe and reliable startup
Starting up the process pump is safe, reliable and easy: When not operating, a spring fixes the diaphragm in a neutral position at all times. This ensures that the diaphragm is never damaged due to incorrect positioning when starting up.
Safety and reliability in extreme operating states
For us, safety and reliability come first: The pump is not subjected to damage, even after operating errors occur or in extreme operating states. We offer maximum protection for user and machine through built-in safety mechanisms—not only when excess primary pressure is present, but also when the pressure or suction line is closed.
