Schego M2k3 Pump Chamber

Description

Schego M2k3 Pump Chamber — Replacement pump chamber for the Schego M2K3 single-outlet air pump

Schego builds its membrane pumps for long service, and in an M2K3 the chamber is the housing where all of that service takes place. Schego M2k3 Pump Chamber (SKU: SH749) is the replacement pump chamber for the Schego M2K3 single-outlet air pump. The chamber is the part of the pump head that holds the diaphragm and the air path to the outlet; if it is cracked, warped or fouled, a new diaphragm alone will not bring the pump back. Schego says its pumps offer long diaphragm life, quiet operation and low vibration, and are used in many industrial applications that need a long service life as well as in aquariums.

The M2K3 is listed at 300 L/h with no head and 260 L/h at 0.5 m, a maximum pressure of 2.0 m of water column, 46 dBA and a case of about 170 × 75 × 60 mm, with a screw regulator and one outlet. It is used for aeration in aquariums, fish transport and bait tanks. This item is the chamber on its own: the supplier lists the air chamber and diaphragm kit (SH743) as a separate product, the diaphragm set (SH742) for the membranes, and the chamber gaskets (SH746) for the seals, and the difference between this chamber and the kit’s chamber is not documented, so the pump should be opened and the old part compared before ordering. Dimensions and material of the chamber are not published. The part is listed for the M2K3 only, not the WS3.

Usage & Application

When to Use

• Cracked head: A split or chipped chamber that leaks air or will not seal.
• Warped by heat or age: A chamber that no longer meets the diaphragm squarely.
• Deposits that will not clean: Residue inside the air path that restricts flow.
• Industrial or transport use: M2K3 pumps working long hours in rough conditions.

Installation & Replacement Guide

• Unplug: Remove the mains plug and disconnect the air outlet line.
• Remove the head: Open the housing and carefully lift the pump head off the body.
• Swap the chamber: Take out the old chamber and fit the new one with fresh gaskets and the diaphragm.
• Close and test: Reassemble evenly and run the pump, checking for steady air and no hissing.
