Schego M2K3 Single Outlet Air Pump 350L/hr 5W

Life in the aquarium is inconceivable without oxygen. Apart from further prerequisites such as heat and light, Schego membrane pumps contribute decisively to an aquarium becoming a habitat. 

Oxygen is vitally necessary for fish and primitive sea species in the aquarium, for they have no CO2 respiration. Leading experts also recommend oxygen as remedy for the regeneration of diseased fish.

All Schego membrane pumps work extremely reliably in continuous operation and are characterized by very quiet running, they have little vibration and are stable. Thanks to more than 70 years experience, high-quality and careful processing are a matter of course.

Long Life membranes, easily changeable prefilters, transparent housing with suspension are additional plus points with all Schego membrane pumps.

Membrane pumps for battery connection 12 V DC
Schego pumps for battery connection enable a supply of oxygen where no mains power is available.

These pumps have been developed for fish and live foods transport. Fish suffer from lack of oxygen during long lasting transports, especially in the summer months, so that the tanks must be aerated. Connecting the air pump to the car battery or to the cigarette lighter is suitable in this case. Therefore the approved 12 V pumps are available with a mounted car battery plug.
In recent years power supply by means of solar cells, especially in the leisure area, has become increasingly popular. Schego pumps in combination with solar cells are very well suited for this application and have proved their worth.

The Schego M2K3 Single Outlet Air Pump is a popular and high-quality air pump from Schego, a German manufacturer known for its durable and quiet aquarium equipment.

• Output: 350 L/hr (liters per hour)
• Pressure: Up to 2.5 meters water column (approximately 0.2452 bar / 3.56 psi)
• Power Consumption: 5 Watts
• Outlet: Single outlet
• Noise Level: Around 36 dBA (very quiet)
• Dimensions: Approximately 170L x 75W x 60H mm (similar to the WS3)
• Flow Adjustment: Manual screw for adjusting air output.
• Durability: Like all Schego pumps, it features long-life membranes, easily changeable prefilters, and robust "Made in Germany" construction.
• Applications: Ideal for providing oxygen to aquariums, operating air-driven filters, and powering protein skimmers. It's suitable for various tank sizes.
• Safety: Australian-approved 240V with an Australian plug (when purchased from an Australian retailer).
• Important Note: As with any air pump, it's highly recommended to use a non-return (check) valve on the airline to prevent water from siphoning back into the pump in the event of a power failure. This is crucial for preventing pump damage and maintaining safety.

M2K3 vs. WS3:

The key difference between the Schego M2K3 and the WS3, both of which offer 350 L/hr output and 5W power consumption, lies in their pressure capabilities.

• Schego WS3: Designed for higher pressure applications, capable of pushing air against a greater head of water (up to 3.5 meters water column). This makes it more suitable for deeper tanks or protein skimmers that require more back pressure.
• Schego M2K3: Offers good pressure for general aquarium aeration and protein skimmers, but its maximum pressure is slightly lower (up to 2.5 meters water column) compared to the WS3.

For most standard aquarium setups, the M2K3's pressure is more than sufficient. If you have a particularly deep tank or a demanding protein skimmer, the WS3 might be a marginally better choice, but both are excellent, reliable pumps.
