ALLWEILER wins project with 435 pumps for the world’s largest PBS plant!

OVERVIEW:

With its 120000 employees, the Hengli Group is a leading company worldwide in oil refining, petrochemical, advanced polyester materials, and textiles. The group owns one of the largest functional fiber production bases and holds an award as “The Environment-friendly Enterprise of Chemical Fiber Industry China.” Currently, Hengli Group and its company Yingkou Kanghui Petrochemical Co., Ltd. are building a new site to produce 800,000 tons of polyester, which includes PBS production, a biodegradable polymer known as green plastic. This is the largest PBS project in the world. Within this project, more than 800 pumps are requested for process applications, heat transfer, and temperature control of the equipment within the plant.

THE CHALLENGE:

For this project, ALLWEILER was approached by our authorized channel partner Nanjing Euro Pump to quote for the thermal oil applications with its high technical and qualitative standards. Since safety is one of Hengli’s top priorities and the technical requirements are high, double mechanical seal pumps were requested. Although ALLWEILER already has many successful references from previous Hengli projects, the challenge was to submit a quotation within the shortest possible time while meeting the technical specification, the delivery time, and the customer’s price level to be prepared for contract negotiation. This was the prerequisite for bearing the great competition from KSB and Ebara.

THE SOLUTION:

Through the excellent cooperation of the EMEA ALLWEILER Radolfzell and the CIRCOR Shanghai team, the customer’s requirements were identified, and the appropriate measures were quickly taken to make positive steps towards placing the order. As double-acting mechanical seals were specified, ALLWEILER quoted its chemical pump type CNH-B with exceptional execution instead of standard thermal oil pumps, and type CWH is used for significant flow rates. Thanks to the great cooperation with the Supply Chain team, the best possible delivery times and capacities were clarified at an early stage, and the customer’s price level could be met through early supplier negotiations, which ultimately set us apart from the competition.
