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.
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.
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.
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.
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.
The triplex series is suitable for almost all liquids thanks to its flexible design. Whether they are dangerous, toxic, abrasive, viscous, environmentally harmful or sensitive fluids, application-specific configuration always gives you the correct diaphragm process pump.
Our patented sandwich diaphragm is not just extremely durable, it is also well-protected. The LEWA DPS diaphragm protection system and diaphragm monitoring system report any damage to the diaphragm before it tears and has a chance to contaminate the pumped fluid.
Our triplex pumps up to the G3R size feature an integrated reduction gear unit and a vertically attached flange motor to save space.
The triplex series fulfills the internationally valid quality standard of the American Petroleum Institute API 675. In this standard, all requirements for a displacement pump in industrial settings are defined with respect to design, construction and performance.
LEWA process pumps achieve the highest efficiency of all pump technologies. Our triplex series also combines high efficiency with low energy consumption.
We comply with globally applicable standards such as VDMA 24284 and 24286-10 when designing our pumps.
With the combination of various pump heads and gear units, the LEWA triplex diaphragm process pump covers a wide performance spectrum. This allows us to provide you with a high-performance, energy-saving pump for any desired application.
The space-saving monoblock design of our triplex pumps ensures maximum efficiency in the smallest space.
We provide various pump heads for different applications. Here, the spectrum ranges from all-purpose variants to special designs for high temperatures, pressures or aggressive fluids.
Universal diaphragm pump head with PTFE sandwich diaphragm for high flow rates. Proven, durable, reliable and with diaphragm position control.
|Flow rate||19 m³/h|
|Operational capability||Metal pump heads (316/316L): can be installed on all ecoflow drive units ≥ LDE
Plastic pump heads (PVC/PVDF/PTFE): can be installed on all ecoflow drive units ≤ LDE
State of the art universal diaphragm pump head with PTFE sandwich diaphragm for maximum operational reliability The patented DPS technology also enables a suction lift cabability that is globally unique in the field of hydraulically actuated diaphragm pumps. Can be installed on all ecoflow pumps.
|Flow rate||6 m³/h|
|Operational capability||Can be installed on all ecoflow diaphragm metering pumps.|
Universal diaphragm pump head with PTFE sandwich diaphragm for extreme pressures. The special geometry of the diaphragm clamping system enables the use of PTFE diaphragms in pressure ranges up to 1000 bar and thus results in a very compact shape. Very economical solution in the range of high pressures, especially in comparison to pump heads with metal diaphragms.
|Flow rate||1,1 m³/h|
|Operational capability||Can be installed on all ecoflow process diaphragm pumps ≥ LDF.|
Proven pump head with metal diaphragm for extreme pressures and high temperatures. Also suitable when a high degree of permeation resistance is required. The diaphragm is working between two contour plates, limiting the deflection of the diaphragm and providing an extreme level of operational reliability. The diaphragm monitoring system offers a plus for safety by immediately displaying the damage of a diaphragm layer.
|Flow rate||0,8 m³/h (M400)|
|Operational capability||M400 can be installed on all ecoflow process diaphragm pumps ≥ LDF.|
Some tasks in process engineering include the metering or circulation of media with critical properties like high temperature and high abrasivity. These critical conditions frequently need to be kept away from the displacer system of the metering pump, either to protect the system or its operating personnel. A normal metering pump is not suitable for such tasks due to its compact design.
|Type||MR / MV / KV|
|Flow rate||19 m³/h|
|Operational capability||Remote pump heads can be installed on all LEWA ecoflow metering and process pumps and on all LEWA triplex metering and process pumps.|
