Functions and technical data

Functions
Technical data
Icon explosion proof version of ITH pneumatic nut runners

No electric power supplies required
Pneumatic motor can be powered by standard air compressors; it can operate in areas where no electrical power is available.

Special version suitable for jobs in explosion-risk areas:
On demand the ITH PDS can be covered with a coating on the gearbox and reaction arm - ideal for applications in the oil and gas industry.

The required torque
is set via the compressed air precision control valve at idling according to the tabular data. The change gear (high and low gear) enables a higher range of rotational speed (optional) and faster work.

Independent rotation between handle and gearbox
ensures steady and optimal positioning of the ITH PDS. Various accessories like extensions, sockets, and special reaction arms are available.

Technical product description

The ITH Nut Runner type PDS is a pneumatic torque wrench including a planetary geardrive which is powered a pneumatic air motor.

For tightening and loosening bolt connections from M10 - M60, 250 Nm to 14,000 Nm. Operated by air power - ideal for places where no electrical power is available or is not permitted like the oil and gas industry.

Design

The torque of the pneumatic motor is multiplied by the compact high-performance planetary gearbox. The standard reaction arm carries the full torque of the reaction. Customized reaction arms (TWIN reaction arm, rotating foot) can be delivered based on customer needs.

Optionally the a change gear is available, due to the change gear the two gears (hi and low) consist in a higher area of preset torque values.

Independent rotation between handle and gearbox ensures steady and optimal positioning of the ITH PDS.

Function description
The desired torque value of the nut runner will be adjusted at the compressed air precision control valve. The value air pressure and torque values are listed in the data table supplied with the nut runner. The torque value can be set in 4 stages at the pneumatic motor (small, medium, high, very high).

Special version suitable for jobs in explosion-risk areas:
On demand the ITH PDS can be covered with a special bronze coating on the gearbox and reaction arm
