Construction

Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation in intermittent operation.

Hydraulics

The outlet on the pressure side is designed as horizontal flange connection. The maximum possible dry matter is 8 % (depending on the hydraulics). Vortex impellers are used as the impeller shape.

Motor

The motors available are surface-cooled motors in single-phase version (with built-in operating capacitor) and three-phase version for the direct starting. The waste heat is given off directly to the surrounding fluid via the motor housing. These motors can operated immersed in continuous duty (S1) and non-immersed in short-time duty (S2) or intermittent periodic duty (S3).

Furthermore the motors are equipped with thermal motor monitoring. This protects the motor windings against overheating. For units with single-phase AC motors this is built-in and switches automatically. I.e. if the motor is switched off due to overheating and then cools down it is automatically switched on again. Bimetallic strips are used for this as standard.

In addition the motor can be equipped with an external sealing chamber electrode for monitoring the oil barrier chamber. This signals if there is water ingress into the oil barrier chamber through the mechanical seal on the fluid side.

The connection cable has a length of 10 m as standard and is available in following versions:

  • With bare cable ends
  • With plug
  • With float switch and plug

Seal

There is a sealing chamber between the motor and hydraulics. This is filled with medicinal white oil. The fluid-side and motor-side seals are provided by two mechanical seals which rotate independently of each other.

Delivery state

  • Submersible sewage pump with 10 m cable
  • Cable version depending on the variant:
    • With bare cable ends (O)
    • With plug (P)
    • With float switch and plug (A)
  • Operating and maintenance manual

Brand

Wilo

As a global player, Wilo is always striving to place the requirements of the customers at the heart of what it does and to find tailor-made solutions for our customers and partner companies. Making. Life. Easy. We use this triumvirate as a basis for developing products and solutions which make people's lives more comfortable in many ways. FROM LOCAL SPECIALIST TO GLOBAL PLAYER Founded in 1872 as Kupfer- und Messing ware Fabrik in Dortmund, Wilo has evolved from being a local specialist to a global player. As the majority shareholder with a stake of approximately 90 percent, the Caspar Ludwig Opländer Foundation ensures the company's continuity and independence. An uncompromising customer-driven mindset, immediate market proximity and, in particular, our culture of innovation have made us who we are; one of the worldwide leading manufacturers of high-tech pumps and pump systems. CUSTOMER REQUIREMENTS AS OUR AIM Wilo always strives to solve problems that have been identified and exceed the customers’ requirements. A high standard, which provides a benchmark for us that we like to be measured by. We examine customer requirements early and from an all-round perspective. Successful inventions are developed at Wilo using our sound knowledge and reliable sense for future technological and market requirements. When both converge, product benefits reach a new level of quality. Intelligence. Inspiration. Innovation spirit. As a pioneer in the pump industry, we focus on anything that moves water. We have the most important prerequisites for continuously setting new standards with Wilo developments, products, systems and services: This includes our international team, comprising experienced and creative employees and cutting-edge technical facilities. WHAT WILO DOES Wilo is a premium supplier for the building services, water management and industrial sectors. Our leading position drives us to maintain our superiority. We make complex technologies user-friendly, simple to operate, energy-efficient and powerful for our customers. In the end, the main focus of everything we do is people.

In all of the segments we are active in, new and powerful pump systems are constantly being further developed and optimised by Wilo engineers, in order to meet the permanently growing and more complex requirements. DORTMUND AS A LOCATION AS A MATTER OF CONVICTION Dortmund has established itself as Wilo’s headquarters. Besides the marketing investments in Borussia Dortmund, Wilo is also now investing significantly in Dortmund as a location. Here, where our success story started the Wilo Campus is now being built – currently Germany’s largest industrial building project. However, it is not an emotional or ideal driving this, it is a tough business decision. The argument for Dortmund is the market proximity to all of the production sites in Europe, the good infrastructure and the availability of well trained staff, so that the site is undisputed as a choice of location given its existing expertise.
