As a replacement to conventional submersible pumps, the manufacturer Hermetic supplied two 8-stage, sealless canned motor pumps. The distinctive feature of the transformation was the customized adaptation of the pumps to the existing plant and its vessels. The pumps were designed for easy installation in the existing tank (with a diameter of 500 mm). The customer, a Swiss fine chemicals manufacturer, thus saves the costly, time-consuming conversion of the existing systems in its production plant.

Chemtech World Expo – February 14-17, 2017 – is one of the largest events for the chemical industry. 600 exhibitors from 20 countries expect up to 40,000 visitors. At the same time eight international conferences and about 150 speakers are offered. In the German pavilion, the German community stand, organized by the VDMA, the company Bungartz will present the concepts of its problem-solver pumps at stand C6A, which also have a high intrinsic safety:
- Wear and corrosion resistant pumps for the fertilizer industry
- Pumps with hydrodynamic shaft seal
- Continuously dry running magnetic driven pumps for liquids with large solids contents
- Cavitation-free pumps with an NPSH value <0.1m
The Sundyne LMV-803Lr is an API 610 compliant pump available in either OH3 or OH5 motor mounting configuration that provides ultra-low NPSHr performance – approximately 5 ft (1.5 m), across the entire performance range – for flows to 800 GPM (180 m³ / hr) and heads to 1,000 ft (305 m).
The ultra-low NPSHr allows the pump to be installed at grade level, eliminating the expense of installation in a pit and performing maintenance in a confined space. The vertical design is ideal for use in refineries, NGL, petrochemical and chemical plants, as well as handling light hydrocarbon handling services, such as bottom pumps for de-ethanizers.
The Swiss pump manufacturer CP Pumpen AG has put a new pump size on the market. The new magnetic drive pump, MKP 250-200-315, enhances the MKP series. These pumps are – according a company’s information – “considered high-performance, energy-efficient, sturdy and very safe – regardless of which medium is pumped. CP’s development team was able to implement all of these product properties in the new MKP 250-200-315.”
“The demand for pumps with a large flow volume had increased in the past. With a volume of up to 750 m3/h, the new MKP is complementing our series with a size that is important for the market”, says Heinz Mathys, Marketing & Sales Director and member of the CP Management Team.
The Swiss pump manufacturer offers a broad range of different gear pumps, predominantly for the chemical process industry. This include the following models:
Kirloskar Brothers Ltd (KBL) launched the technologically advanced GK-P pump series. GK-P is a process pump used for handling various types of chemical liquids from various process industries. It is an end suction centrifugal process pump having discharge capacity upto 500 m³/h at 1450 rpm. With a size ranging between 25 mm to 150 mm, the pump can handle temperatures in the range of -50 ⁰C upto +350 ⁰C. The wide range of smooth hydraulics will meet the customers’ requirements and promote better efficiency of the product. The back pullout design will help in easy and quicker maintenance.
The new Wilden air-operated double-diaphragm (AODD) pump series 430 and 830 Advanced FIT is produced of 316 stainless steel for higher corrosion resistance in aggressive chemical applications. These sieries have been specifically designed to be direct replacements for existing Wilden 38 mm (1-1/2”) and 51 mm (2”) Advanced pump installations.

In the existing chemical installation in a Wacker Chemie plant, the safety-related design of the relevant pump systems had to be thoroughly renovated. One of the basic requirements for the redesign was that diaphragm pumps themselves had to remain absolutely hermetically tight, even at high working temperatures of +170 °C during normal operations and brief peaks as high as +200 °C. As a result, Lewa developed an individual solution to meet the specific customer requirements.
“As an additional security measure, the pressure-free hydraulic reservoir behind the diaphragm is blanketed with nitrogen as a protective gas”, explains Lewa project lead Rainer Sonnenfroh.
KEPL has introduced energy efficient BB1 series pump under the model name of KBAD. This new series is designed especially for process industries for various chemical and liquid pumping applications. The “Between Bearing Axially Split Case Pump” is conform to API 610 latest edition.
The RCE pump is a chemical pump made of metallic materials. It is developed for heavy-duty applications in chemically aggressive and abrasive media with or without a solids content, in chemical processing technology, the primary materials industry and other areas of industry. Typical applications are molten salt, pitch, tar, sulphur, etc.
