Marine centrifugal pump APM 100

The Marina APM 100 centrifugal pump is a reliable self-priming unit specially engineered for lifting water from great depths and ensuring stable operation even with significant fluctuations in water level. Thanks to the external ejector, the pump can draw water from depths of up to 35 meters, making it a versatile solution for autonomous water-supply systems, household applications, wells and domestic installations.

The model is highly durable, resistant to pressure variations and operates almost silently. It is especially effective in pressure-boosting systems, when supplying water from wells with a diameter of 100 mm or larger, as well as in domestic plumbing networks with unstable pressure.

Key Technical Features of Marina APM 100

▪️ Self-priming centrifugal pump with external ejector

▪️ Pre-set pressure switch: 1.6–3.2 bar
▪️ Continuous-operation mode, stable water delivery
▪️ Quiet operation and high reliability during prolonged use
▪️ Efficient performance despite abrupt changes in water level

Application Limitations

▪️ Maximum liquid temperature: up to 35°C
▪️ Ambient temperature: up to 40°C
▪️ Maximum suction height without ejector: 8 m
▪️ Mechanical impurities — minimal

Where the Marina APM 100 Pump Is Used

Thanks to its external ejector, the pump is ideal for:

▪️ autonomous water-supply systems for houses and cottages
▪️ lifting water from deep wells and boreholes with diameter ≥100 mm
▪️ water supply from tanks, reservoirs and rainwater collectors
▪️ garden, orchard and greenhouse irrigation
▪️ vehicle washing and household applications
▪️ pressure boosting in domestic plumbing
▪️ situations where installing a submersible pump is not possible

The external ejector allows the station to lift water from great depths by using part of the pumped flow as driving energy — making this one of the most reliable and efficient technologies among self-priming systems.

How does an external-ejector system work?

When the well depth exceeds 8–9 meters, conventional surface pumps are unable to operate properly. In such cases, the Marina APM 100 system is used:

▪️ The pump sends part of the water back to the ejector.
▪️ The ejector creates a vacuum deep inside the well.
▪️ This vacuum lifts the water to the surface.
▪️ The total volume of pumped water always exceeds the flow redirected to the ejector.

This makes the pump ideal for deep sources and unstable aquifers.

Marina APM 100 — the perfect solution for deep lifting

A reliable, quiet and powerful self-priming centrifugal pump with an external ejector, capable of lifting water from depths up to 35 meters. It is perfectly suited for autonomous water-supply systems, pressure boosting and domestic applications, ensuring stable operation even with fluctuating water levels.
