Fluid Control New Performance Rating Added to Diaphragm Metering Pump Series

| Editor: Ahlam Rais

Lewa’s Ecoflow series is suited for metering a wide range of fluids - even hazardous, toxic, abrasive, viscous or critical media. The new drive unit model, LDZ, which is designed for a hydraulic output of 15 kw, is intended to close the gap between the LDG (6 kw) and the LDH (20 kw) sizes.

Just like the other models in the series, it can be used as a single or multiplex drive unit and, thanks to its modular system, can be tailored to the customer's needs, opines the firm. Among the five pump head types, there are also designs available for use in the food and pharmaceutical industries. During development, special attention was paid to optimizing the components with regard to the manufacturing process, states the company.

The resulting cost-benefits can be passed on to the customers. At Achema 2018, the company will be presenting the new model in triplex design with three different pump heads. According to the company, a more in-depth experience will be made possible by an augmented reality animation that gives the viewer a glance into the inside of the pump.

The gap between the company’s LDG and LDH Ecoflow process pump drive units is relatively large. Hence, when there was a demand for a pump just slightly more powerful than the LDG, the sales and product management initiated the development of a new performance rating that was meant to function as an intermediate unit; the LDZ at 15 kw, explains the organisation.

The Research and Development Department called upon internal divisions such as assembly and the service and purchasing departments to make the product market-ready in the shortest amount of time possible. Various worm shaft bearing concepts were analyzed regarding service life, heat development, price, manufacturing and assembly. The cast parts, which are subject to a complex manufacturing process, were designed with process reliability in mind.

One Pump - Countless Applications

The new size allows the firm to be more flexible and meet different requirements. The pump is available as a single or multiplex drive unit and can be combined with other types from the Ecoflow portfolio. The firm claims that with a hydraulic output of 15 kw and a flow rate of up to 18 m3/h, the new process pump can handle many applications in areas that include the chemical and the petrochemical industry as well as refineries.

These industries work with corresponding media and high-pressure processes and require the machines to run reliably and precisely 24/7 all year long. In addition to process industries, the LDZ is used in the oil and gas sectors, such as for a variety of condensates or injection packages for chemicals. There are no system requirements for using the pumps in this way.

Exhibit with Augmented Reality Function

Like most other models from the Ecoflow modules, the LDZ can be customized to individual applications. This customization means that wetted materials and process valves can be adapted specifically to the pumped fluid as needed, explains the firm. Furthermore, implementing a heating or cooling jacket or a remote head solution is possible at extreme temperatures.

A total of five different pump head types are available. The pump can also be adapted to the food and pharmaceutical industries. Customized constructions are also available for special requests that are not yet available in the product range.

At Achema, the company will present the new model size; a multiplex pump equipped with three different pump heads. The firm states that the remote pump head is suited for high temperatures in refineries. On the other hand, the M800, the firm’s high-pressure pump head (up to 1,000 bar) is being used to handle enormous pressures, such as those in reactor pumps. The model is completed by the M900, the company’s pump head for a wide variety range and high flow rates.

The M900 design on display is the hygienic version for the food and pharmaceutical industry. In order to get a better understanding of the pump, the organisation is making an augmented reality app available on a tablet. It shows the inside of the exhibit in 3D and uses animation to simulate the functionality of the pump and various operating conditions. This way, those interested can get an insight of the functionality.
