Top Reasons to Choose LEWA triplex® for High-Pressure Processes

The LEWA triplex stands out as a hydraulically driven diaphragm process pump with a compact design, delivering multiple advantages over similar pumps in high-pressure processes.

Compact and space saving design of pumps and systems

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.

Absulute safe start up at LEWA triplex 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.

Pumps suitable for a wide range of fluids

Suitable for virtually all fluids

The ecoflow series is suitable for almost all liquids thanks to its flexible design. Whether they are dangerous, toxic, abrasive, viscous, environmentally harmful or sensitive fluids, the user-specific configuration always gives you the correct diaphragm process pump.

Hermetically tight, leakfree diaphragm pumps

Patented sandwich diaphragm

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.

Integrated pressure relief valve

A pressure relief valve in the hydraulic part of the diaphragm pump prevents potential overload situations during operation. This valve is individually adjustable and can therefore be adapted to different operating situations.

Vertical flange motor

Our triplex pumps up to the G3R size feature an integrated reduction gear unit and a vertically attached flange motor to save space.

API 675 standard

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.

Low maintenance costs and a long service life

Our pumps feature extremely low maintenance costs and a long service life. If regular maintenance intervals are maintained, our diaphragm pumps can operate up to 40 years.

High energy efficiency

LEWA process pumps achieve the highest efficiency of all pump technologies. Our triplex series also combines high efficiency with low energy consumption.

Worldwide standards

We comply with globally applicable standards such as VDMA 24284 and 24286-10 when designing our pumps.

Hermetically sealed

Diaphragm pumps work without dynamic seals. This forms a hermetically sealed working area. No emissions escape to the outside, and contamination of the fluid is impossible.

LEWA Smart Monitoring

With digital pumps for more efficiency, system availability and profitability of the entire production.

LEWA Smart Monitoring is a monitoring system consisting of sensors, a programmable logic controller (PLC), an industrial PC (IPC) and data analysis for new and existing pumps. The system determines characteristic values and key performance indicators. There is no intervention in process control or direct contact between the sensor system and the conveyed fluid.

With key performance indicator-based condition monitoring, you detect and monitor operating statuses proactively. You can also optimize the overall output and robustness of your pump and pipe systems. This will increase the efficiency of your entire production plant. You can access the data conveniently via your corporate network. Or you use the LEWA cloud with extended analysis and service offers.

LEWA triplex G3M Process Pump: Interview with CMO Stefan Glasmeyer

LEWA introduces the new triplex process diaphragm pump G3M. With its compact monoblock design and the engine concept with a one-piece crank shaft, the new pump is very efficient. Compared to previous solutions, up to 30 percent footprint and weight can be saved. Thus, the G3M is particularly suitable for applications where space and weight play an important role, e. g. on offshore platforms.At ACHEMA 2015, LEWA CMO Stefan Glasmeyer talks about the advantages and the enormous market potential of the G3M process diaphragm pump.

Customized valves

LEWA uses numerous special types of valves such as specially hardened valves for liquified gases or valves with minimal dead space for the food and pharmaceutical production.

Diverse connection geometries

Our pumps are equipped with all common connection geometries such as DIN standard, BASF's high-pressure standard, American ANSI, JIS, or your individual requirements. Customized configurations are possible.

Integration into process control systems

The signal acquisition of process control systems is achieved analogously or digitally. Flow rate is adjusted via electric or pneumatic stroke adjustment, alternatively by motor drive (FU).

Diagnostic connection

Our pumps and systems have connections that facilitate the diagnosis of their performance. This is done by a service technician on site or via remote monitoring.

Heating and cooling jacket

With heating and cooling jackets, our pumps are suitable for almost any temperature and can convey fluids at low temperatures or extreme heat.

Integrated pressure relief valve

An integrated pressure relief valve prevents potential overload situations. The valve is individually adjustable and can be adapted to different operating situations.

Special design materials

If the process demands it, wetted parts such as pumps heads and valves will be made of special materials such as stainless steel 1.4401/1.4404 (AISI 316/316L), Hastelloy or Duplex steel and PVC.

Sanitary & hygienic Design

LEWA pumps and systems in sanitary & hygienic design are available for applications that require extremely high purity, such as food production and the pharmaceutical industry.

CIP and SIP capability

Many LEWA pumps, systems and units can be cleaned (Cleaning in Place) and sterilized (Sterilization in Place). To carry this out, it is not necessary to disassemble the equipment.
