Product No.: 98626076

Non-self-priming, single-stage, centrifugal pump designed for handling wastewater, process water andunscreened raw sewage.The pump is designed for intermittent and continous operations in submerged installation. Therevolutionary S-tube impeller provides free spherical passage of solids up to 50 mm and is suitable forwastewater with a dry matter content of up to 3 %.A unique stainless-steel clamp assembling system enables quick and easy disassembly of the pumpfrom the motor unit for service and inspection. No special tools are required. Pipework connection is viaa DIN flange.

Further product detailsTypical application is transfer of liquid, such as:

- large quantities of drainage and surface water- domestic wastewater with discharge from toilets- wastewater from commercial buildings without discharge from toilets- sludge-containing industrial wastewater.

The pump is ideal for pumping of the above liquids from for instance:- municipal network pumping stations- public buildings- blocks of flats- factories/industry.

The pump is suitable for both temporary and permanent installation either as free-standing on ringstand or on an auto-coupling system.

PumpThe pump housing, motor top and impeller are made of cast iron (EN-GJL-250).All surfaces of the cast iron parts are protected with cataphoresis coating. The surface of the cast ironpump parts is afterwards painted with environmental friendly powder coating (type NCS 9000N (black),gloss code 30, thickness 100 m) which ensures high impact and corrosion protection. The final pumpis assembled from already painted parts which ensures that no rust or scale can be formed in groovesbetween parts, etc.The S-tube impeller is providing free spherical passage through the impeller and pump housing andcreates a natural extension of the pipework connected to the pump. The S-tube impeller is awet-balanced and tube-shaped channel impeller placed in a pump housing that matches the smoothtube shape leaving no obstructions or dead zones.The key to the S-tube design is simplicity, with no cutting or moving functions that can get worn overtime, thereby ensuring constant, superior efficiency. The simple design means lower life cycle costsbecause abrasive wear is reduced and there are fewer clogging incidents.

The shaft seal consists of two mechanical seals that ensure a reliable sealing between the pumped liquid and motor.The shaft seals are incorporated in a single-unit cartridge shaft seal system that is easy to replace in the field withoutuse of special tools.The combination of the primary and secondary seals in a cartridge shaft seal system results in a shorterassembly length compared to conventional shaft seals.

- Primary seal: Silicon carbide/silicon carbide (SiC/SiC)- Secondary seal: Carbon/Ceramics

The shaft seal is bidirectional, meaning it operates correctly in case of backflow through the pump.

The pump is approved according to CE, EN12050-2.MotorThe motor is a watertight, totally encapsulated motor supplied with a 10 m power cable. The stainlesssteel plug is fastened with a union nut. This nut and the O-rings provide sealing against ingress of theliquid.The plug is polyurethane-embedded, ensuring a watertight and durable seal around the leads of thecable. This prevents the ingress of water into the motor through the cable in case of cable breakage oradverse handling in connection with installation or service.A compact motor construction with a short shaft reduces vibrations, resulting in an increased efficiencyand lifetime of the shaft seal and ball bearings.The motor features built-in thermal protection to protect the motor against overheating and ensure thereliability.The pump is equipped with the following sensor(s):

- A digital moisture switch that is fitted in the motor chamber monitors whether water enters themotor chamber. If moisture is detected in the motor chamber, the switch will trip and send awarning to the sensor module.

The pump is designed for speed-controlled operation to keep the energy consumption at a minimum.To avoid the risk of sedimentation in the pipes, we recommend that you operate the speed-controlledpump within a speed range of 30 % to 100 % and at a flow rate above 1 m/s.
