ApplicationsScanpump process pump BE is the core product range for pulp and paper applications, e.g. - paper, tissue and board ma-chines, chemical-, mechanical- and recycled fibre lines, chemi-cal recovery as well as effluent treatment plant etc.

They are also very well suited for general industry and waste-water applications.

Design

The BE series includes 39 pump sizes and is built on a modular design, which offer high interchangeability, simplified service and a low number of spare parts. This means that low mainte-nance costs can be obtained.

Pump casingRugged BE pump construction creates longterm wear resist-ance. The generous wall thickness and the casing’s smooth, pocket-free interior protect against erosion and corrosion.

ImpellerThe impellers can handle almost any suspensions and a huge range of slurries. The pumps are available with semi-open impellers. A new hydraulic design for semi-open impellers features large free passages. The sturdy construction ensures high wear resistance, resists corrosion and reduces sensitivity to foreign objects.

When the BE pump is used as medium sized fan- or dilution pumps, ESDF impellers, special low pulsations impellers are used.

For some sizes vortex impellers can also be selected. These impellers have an improved vane design offering clogless and trouble-free operation.

A hexagonal shaft secures the impeller fixing, giving stable operation conditions and long MTBF (Mean Time Between Failure).

Wear discThe wear disc is replaceable and can be easily adjusted from the pump casing’s front. This makes it easy to maintain high efficiency over the entire lifetime of the pump and ensures shorter MTTR (Mean Time To Repair). The sealing of the pump casing has also been improved.

Your benefits

* Large energy savings. Improved hydraulic design creates greater efficiency in each individual pump minimising the average power consumption.

* Total reliability. Robust design, secure impeller fastening and sturdy bearing assembly ensure long pump lifetime. Better performance coverage for better runnability gives exceptional MTBF.

* Simplified service. Smart pump design with maintenance-reducing features. Modular construction with few parts to service and store.

Shaft The shafts are sturdy, with a deflection of less than 0.05 mm at the seal areas under normal running conditions. All shafts are protected by a replaceable sleeve in stainless steel or higher quality alloys.

Shaft sealsThe alternatives include single and double mechanical seals, gland packing and dynamic seals, with a variety of material to suit every application.

Bearing assemblyThe bearing assembly of a BE pump features a sturdy design that ensures long MTBF, long pump lifetime and low mainte-nance costs. Six different bearing sizes cover all pump in the series, and all bearings have angular contact ball bearings at the driven end.

Standard bearing assemblies are lubricated with grease, though oil is also an option. On oil-lubricated bearing assem-blies, two inspection eyes are standard. This makes it easy to inspect the bearing assembly from both sides.

ApplicationsNL pumps are designed to endure the constant demand of general-purpose applications involving clear or turbid liquids and water treatment positions. These pumps are also suitable for explosive atmospheres. The NL can even handle liquids with temperatures of up to 170°C. The NL range offer reliable per-formance for many crucial applications within industry, water and wastewater and building services.

DesignThis versatile pump is available in a range of 50 sizes with 5 dif-ferent bearing assemblies. Horizontal, single-stage centrifugal pumps with connections and main dimensions according to DIN 24255 / EN 733 plus 19 additional sizes.

The range includes horizontal centrifugal pumps with dis-charge diameters from DN32 to DN300.

The variety of materials and shaft seal options permits pumping of many liquids under different operating conditions.

High reliabilityThe NL pumps are of robust design and offer prolonged MTBF (Mean Time Between Failure) thanks to oversized ball bearings and a reduced shaft deflection which complies with ISO 5199. The bearing assembly is rigid in its design. The bearings are available with grease or oil lubrication.

Modular designThe modular system ensures high interchangeability of major parts, which results in reduced spares inventory, easier dis-mantling and assembly. All this minimises down-time.

The design of the pump also allows the rotor unit to be with-drawn without disturbing the pipe work. Using a spacer type coupling, permits back-pull out of the rotor assembly from the pump casing without moving the motor.

High efficienciesNL pumps benefit from the latest technology and have very high efficiencies - with peak efficiencies over 89%. The unique hydraulic design improves flow rates and also helps to reduce the power consumption. The impellers are of closed design and offer unique hydraulics with higher flow rates and better efficiencies.

Many optionsThe NL-pumps are available in a variety of shaft seals with dif-ferent options. These seal arrangements are gland packing or single DIN type mechanical seal with or without quench and ex-ternal flushing. This permits pumping of a wide range of liquids.
