Dry installing a pump has many benefits, but makes for a more complex installation. There are some key principles that must be adhered to in order for dry pump installation to work without issue.
The AquaMax Eco Dry Premium pump operates by flooded suction. This means that the pump must be permanently flooded with water in order to prime. In a dry installation set up, this requires the pump and the pipe connected to the suction inlet to be below the water level of the pond or tank the water is being pumped from, so that water fills both the suction pipe and the pump by gravity. For this to be possible, the suction pipe must pass through the pond liner or tank wall below the water level. The suction pipe cannot be routed up and over the pond or tank wall, and the pump cannot be positioned above the surface water level of the tank or pond. The outlet pipe can be routed anywhere within the pumping limitations of the pump.
Stepped Hose Tail fittings are provided for both the inlet and outlet, which allow a number of different flexible hose sizes to be connected. It is very important that the pipe connected to the suction inlet is not of a lesser diameter than the pipe connected to the outlet. For simplicity, try to use the same size of pipe on both sides to ensure balanced flow, unless circumstances dictate otherwise. Solid pipe can be used as an alternative to flexible hose as long as the same pipe sizing principle is followed. When using solid pipe, ensure that isolation valves and unions are installed so the the pump can be separated from the pipework system for maintenance.
It is also very important that a suction strainer attachment is connected to the end of the suction pipe. This ensures that no large objects can be sucked into the pump, potentially damaging the inner workings, and also prevents wildlife such as fish newts and frogs from entering the pump. The suction strainer should however allow for organic waste to be processed through the pump if the pump is being used as part of a pond filtration set up, so an appropriate suction strainer should be chosen for the task. The suction strainer should ideally be fairly large in size so that the inlet is not restricted by the strainer, either when clean, or partially soiled. A strainer hole size of 6-11mm would be appropriate. The OASE Large Satellite Strainer is a good strainer for use with these pumps.
The drawing below shows an AquaMax Eco Premium Pump in a dry installation with a strainer on the suction pipe.

The AquaMax Eco Dry Premium Pump is mounted in a special base with the motor firmly secured by a clamp bracket for stability. The base can be screwed down to a hardstanding if necessary. The pump outlet can be configured in two different positions by removing the 4 screws that hold the housing in place. The outlet can be directed horizontally to the right, with a 90 degree clockwise rotation, or vertically, with a 90 degree anticlockwise rotation. The suction inlet will always be positioned horizonal at the front of the pump.

The AquaMax Eco Premium can also be used as a submersible pump by refitting the exterior strainer parts if the situation later required a change of installation method. These parts are all supplied with the pump as standard.

The OASE Environmental Function Control (EFC) is a protective technology incorporated into the motor of the AquaMax Eco Premium pump to prevent the motor being damaged should the pump become blocked up or begin to pump dry. The EFC performs a check for acceptable pumping conditions instantly upon starting the pump and then performs regular checks throughout the period of operation. If a fault in the system is detected during a check, the pump will cease to run, preventing the motor from overheating and burning out. Once the problem has been resolved, the pump will test again, and proceed to operate again. This innovative feature ensures the safety and longevity of the pump in the event of a crisis such as a complete rotor jam or a prolonged dry-running spell.
This generation of the OASE AquaMax Eco Premium Pump can be connected to the OASE Control devices to enable switching and speed regulation to be done remotely, either by control box, or on the OASE Control App. There are 3 control devices that are compatible with the AquaMax Eco Premium range of pumps:
OASE Eco Pump Control (Outdoor Switch). This device is a digital control box that can be plugged directly into the rear connector on the AquaMax Eco Premium pump to enable switching control and regulation remotely. The control box is weatherproof and can be installed outside. This device does not require a separate power supply, as it is powered by the pump when connected via its own 10 metre control cable. This device enables on/off switching, speed and power regulation and switching of the Seasonal Flow Control function. The display screen also provides information such as current speed and power use, total running hours, and alerts when the pump has a problem such as a blockage.
OASE InScenio FM Master EGC Cloud (OASE Control App). This device is a weatherproof 4 way socket device that can be used to provide power to the pump (and additional electronic devices) via 4 plug sockets, and also enable the pump to be controlled electronically on the OASE Control App (by connecting the pump to the FM Master unit via the EGC port, using an EGC Connecting Cable).
OASE Cloud Control (OASE Control App). This device can be used to connect the AquaMax Eco Premium pump to the OASE Control App. This device acts only as a Wi-Fi receiver (it does not provide power) and can be plugged directly into the rear control connection on the pump motor if the pump is dry installed, or connected via a longer EGC cable for underwater installations.
The OASE Control App enables smart control of any device that is compatible with the OASE Control system, either within a limited range of the Wi-Fi receiver (FM Master/Cloud Control), or with a limitless range if configured for Cloud access. The features of the OASE Control App (relevant to the AquaMax Eco Premium pump) include on/off switching, full speed and power regulation, switching of the Seasonal Flow Control function and timer settings, all from a compatible smart device (phone or tablet) The OASE Control App will also provide alerts by text/email if there is an operational issue with the appliance that requires attention.
If an OASE EGC system is already installed, an OASE Control Adapter can be connected to the AquaMax Eco Premium pump to provide a 2 way EGC connection in and out of the pump, allowing this to be incorporated anywhere within the existing OASE EGC circuit.

Seasonal Flow Control (SFC) is an OASE patented, power saving technological feature that allows the temperature of the water to dictate the speed of the pump. There are 3 speed levels (Minimum, Medium and Maximum) which are activated at different water temperatures. This facility is designed to save energy by reducing the speed/power consumption of the pump when the water temperature is cooler and the pond volume does not need to be turned over as frequently.
The SFC facility can be turned on or off depending on its requirement, either via the switch on the side of the motor, or electronically if the AquaMax Eco Premium pump is being controlled using one of the OASE electronic control devices.
If the SFC is turned off, the pump will operate at a fixed speed (maximum output with no digital controller, or the set speed on the digital controller if one is being used) and will not change, regardless of the water temperature. If the SFC is switched on, the pump will operate at Maximum speed when the water temperature is around 17°C or higher, Medium speed when the water temperature is between 10°C and 17°C, and reduce to Minimum speed when the water temperature falls below 10°C.
Each speed level decrease results in a considerable lowering of the power consumption for the duration of the operating period, which means energy is used most efficiently and is not consumed unnecessarily. This feature sets the OASE AquaMax Eco Premium pump apart from any other pond filtration pump on the market when it comes to technical innovation and energy efficiency.
The charts below show the different flow curves for each speed level of SFC and the power constmption for each speed level.
