Boxer S - diaphragm pump for gases

The most popular of the Boxer range, this pump has proved itself as a primary component in many thousands of laboratory pipetting equipment and personal gas detectors.

 

As with the Micro-Boxer, the Boxer S is available with either the permanent magnet DC motors or with the core-less motors.

 

The design has been optimised to offer a good performance at minimal current requirement. A typical Boxer S pump equipped with a core-less motor will, for example, consume merely 18mA  for an air flow of 0.8l/min at 4.5V supply and will start and work at environmental  temperature of –20ºC (-4F).

A unique feature of the Boxer pumps is the ability to mount the pumps as a push fit into your equipment. The pump has been designed to fit tightly onto the crank-case lid. The lid in this case acts as a fitting accessory for the pump.

Fitting the pump via the lid onto your equipment, allows you to remove or replace the pump without the need of any tools. Just push the pump onto the lid and pull it out whenever desired.

This feature also allows for the pump to be fitted onto surfaces which do not allow back access to the fixing screw heads.

The Boxer S pumps have 6 fixing holes and the Boxer D has 8 fixing holes for your choice. Normally two fixing screws are sufficient to secure the pump into your instrument.

The crank-case lid has two blind fixing holes for No. 2 self tapping screws and two through holes for M2 machine screws. You can use the two M2 machine screws in order to fix the crank-case lid either from the outside or the inside of the instrument.

The two other fixing  holes (four for the D range), are on the side plates of the pump. These holes are 10mm deep
