Construction

Submersible sewage pump as submersible monobloc unit for stationary and portable wet well installation, as well as stationary dry well installation.

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 and single-channel impellers are used.

Motor

The motor versions used are single-phase current and three-phase current surface-cooled motors. For single-phase current motors, the condenser is installed in a separate switchgear. Depending on performance, activation is carried out via direct startup or star/delta startup.

The motor is cooled by the medium around it (pumped fluid or air). The waste heat is dissipated via the motor housing.

The motors can be immersed during continuous duty (S1). In submerged operation, the operating modes S1 (continuous duty), S2 (short-time duty) or S3 (intermittent) are possible depending on the rated motor power.

Furthermore the motors are equipped with the following monitoring devices:

  • Leakage detection motor compartment: The leakage detection signals water ingress into the motor compartment.
  • Thermal motor monitoring: thermal motor monitoring protects the motor winding against overheating. Bimetallic strips are used for this as standard.

The motor can also be fitted with an external sealing chamber electrode to monitor the sealing chamber. This signals if there is water ingress into the sealing chamber through the mechanical seal on the fluid side.

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

Seal

Located between the motor and hydraulics is a sealing chamber with the seal on the fluid and motor side. This sealing chamber 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
  • 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.

All Wilo pumps and systems in your segment are in a highly technological state and specialised, to fulfil specific requirements. WILO INDUSTRY The supply of industrial enterprises is a very extensive and economically complex segment with highly specialised pump systems. Wilo proved itself in this area decades ago and has remained true to its principles by constantly adhering to all of its high quality requirements. WILO OEM In the OEM segment, Wilo offers a high-efficiency and cost-conscious product portfolio in addition to tailored services. Here, products in the sectors of cooling, heating, solar thermal energy, geothermal energy and sanitation are being constantly adapted to customer wishes and requirements. 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.
