Product group N.

Product catalog summary

Overview
This document provides a detailed description of the product group N, specifically focusing on coupling rods for power transmission and standard pumps. The pumps are designed for conveying a wide range of media, from thin to viscous, with or without solids, across various industrial sectors.

Specifications
- Joint Connection: Composed of 5 components, featuring wear-resistant, hardened, and replaceable parts for easy repair.
- Dry Running Protection: Thermoelectronic protection (TSE) is available to prevent stator damage.
- Stator: Features integral elastomeric seals to prevent corrosion, with optional adjustable retensioning device.
- Rotor: Made from wear-resistant and corrosion-proof materials with additional surface treatment.
- Tie Bolts/Screws: Corrosion-proof, with optional stainless steel design.
- Universal Joint Sleeve Protection: Stainless steel protection against mechanical damage, optional.
- Inspection Ports: Optional on both sides.
- Pressure Branch: Connection for pressure/vacuum gauge with DIN or ANSI flange connections.
- Suction Casing: Designed for smooth flow with large cross-section, rotatable flange connections.
- Universal Joint Sleeve: Protects grease-filled joints, designed to reduce turbulence and NPSHr.
- Lantern: Connects pump and drive, securing assembly.
- Shaft Sealing: Options include gland packing or mechanical seals.
- Drive: Options include geared motors, variable speed drives, or hydraulic motors.
- Plug-in Shaft Connection: Facilitates easy dismantling and replacement of parts.
- Drive Casing: For range NS, allows relubrication and features double bearing seals.

Features
- Minimal pulsation and controlled flow, eliminating the need for pulsation dampers.
- Self-priming capability, even with air or gas liquid mixtures up to 9 m.
- Versatile installation options, with horizontal or vertical mounting.
- Gentle conveyance of products with solids.
- Reversible direction of rotation and fluid flow.
- Conveying capacity ranges from 30 l/h to 500 m3/h, with pressure up to 48 bar.

Range Details
- BN Range: Features a directly flange-mounted drive, eliminating the need for a separate pump bearing, making it compact and cost-effective.
- NS Range: Offers a universal drive configuration with a drive casing and free shaft end, simplifying maintenance.

Applications
The pumps are suitable for a wide range of industries, including agriculture, ceramics, chemical, construction, food and beverage, mining, oil production, pharmaceuticals, and more.

Conclusion
The document highlights the versatility and efficiency of the product group N pumps, emphasizing their ease of maintenance, adaptability, and suitability for various industrial applications.

N – Standard pumps The two ranges of pumps within the product group N form the basis of all seepex progressive cavity pumps. They are available with various rotor/stator geometries (conventional, 6L, and Tricam) and can be applied in virtually all industrial sectors – for conveying thin to viscous media with or without solids. Joint connection consisting of just 5 components. Power transmission through wear resistant, hardened and replaceable joint parts: easily repaired. Dry running protection TSE, thermoelectronic prevents the stator from being damaged by dry running, optional available. Pressure...

Universal joint sleeve with holding bands protects the grease-filled joints from penetration of the liquid pumped, even in case of maximum vacuum or pressure loading; streamlined design to reduce turbulence and NPSHr. Shaft sealing gland packing with or without flushing/seal cage ring or single or double mechanical seals. Drive geared motors, variable speed drives or hydraulic motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Lantern for connection of pump and drive and to secure the assembly to the baseplate or directly to the foundation....

Why standard pumps? Because they are used in applications such as agriculture, ceramics, chemical and biochemical industry, construction, dyeing and varnishing, electroplating, environment technology, fish industry, food and beverage industry, mining, nonmetallic minerals, oil production and offshore technology, petrochemicals, pharmaceutical and cosmetics industry, pulp and paper industry, shipbuilding, sugar industry, supply and waste disposal industry, textile industry, vehicle construction and equipment and wood processing industry. Features • Minimal pulsation, controlled flow, so that no...

Overview of ranges The drive of BN range pumps is directly flange-mounted to the pump. This means that a separate pump bearing is not necessary and the pump is more compact and less expensive. The plug-in shaft connection between drive and the rotating unit simplifies the replacement of rotating wearing parts and the shaft sealing, thereby making the BN range very service-friendly. Range BN In pumps of the NS range the drives are not directly flangemounted in favour of a universal configuration of the drives. They have a drive casing and a free shaft end, an elastic coupling or a V-belt and a...
