Series NTP

Product catalog summary

Overview

The document presents technical information about the NTP series of pneumatic linear vibrators designed for industrial applications such as loosening adhering materials in hoppers, silos, containers, and aiding in vibration tables and chutes. These vibrators generate linear vibration through a differential pressure piston and are available in various versions including ATEX-compliant and stainless steel models.

Product Features

Nominal frequency range: 1,328 to 11,160 min^-1
Centrifugal force range: 69 N to 2,039 N
Frequency and amplitude are separately adjustable
Versions available with elastomeric impact plates (rubber hammer effect), air cushion operation (quiet), or hard impact
Oil-free operation possible following manufacturer recommendations
Available in ATEX-compliant and stainless steel housings

Operating Principles

The vibration is produced by a freely oscillating differential pressure piston. In the standard B+C version, the piston strikes an elastomeric impact plate creating a rubber hammer effect. The B version operates quietly with the piston working against an air cushion, while the B+A version provides hard impacts.

Frequency is infinitely variable by adjusting the operating pressure. A directional valve is required for operation but is not included.

Technical Specifications

Operating pressure: 2 to 6 bar
Operating temperature range: 5 °C to 60 °C
Compressed air or nitrogen supply with filtration ≤ 5 µm, preferably with mist lubrication

NTP 48	194	100	78	3.95

Applications and Recommendations

The NTP series is ideal for industrial processes requiring vibration to dislodge materials or assist in emptying containers. The choice of version depends on the required impact type—soft rubber hammer effect or hard impacts. Proper air quality and pressure regulation are critical for optimal performance and longevity.

Accessories for mounting, installation, and control are available from the manufacturer.

Subject to technical modifications. Application areas The pneumatic linear vibrators of the series NTP are particularly suitable for knocking off firmly adhering substances in hoppers, containers, silos and bunkers. They are also used as drives for vibration tables and chutes, as well as an emptying aid for containers. NTP vibrators can achieve the effect of a rubber hammer impact, or can function with hard impacts. Design...
