Mauzer, an IBC tank with a capacity of 1,000 liters in a protective steel pallet, has become one of the most popular water reservoirs on plots, farms and construction sites. The problem comes when you need that water from there extract under pressure – for watering, washing, feeding a drip installation or pumping to another tank. In this guide, as a team from Dambat, a Polish pump manufacturer, we show you how to choose pump for Mausers so that it physically fits in the hole, works stably and does not seize after one season. All parameters we provide come from the catalog cards of our brand pumps IBO – not by guesswork.
The most important limitation: pump diameter and Mauser flap
Before we even get to capacity and lift height, there's a purely mechanical issue to address. The Mauser has an upper inspection flap inner diameter 155 mm. This is a hard boundary – none pump for Mauser lowered by this flap cannot have a larger body diameter. In practice, you need to leave a margin for the cable, safety rope and delivery hose, so the more space there is, the easier the installation and service.
For example, ours submersible pump Multi IP 1000 AUTO (1 kW, 230 V) has a diameter of 150 mm. This means that it will fit in the 155 mm hole, but it will be tight - the pump will practically fill the flap and lowering it with the hose installed requires attention. If you care about comfortable installation and free circulation of water around the body, it is worth considering slimmer designs, such as our NEPTUN series pumps with a diameter of only 102 mm or 4" submersible pumps with a diameter of approx. 100-124 mm. We write about each of them below.
submersible pump or submersible pump for Mauser?
Two families of devices fit the IBC tank: submersible pump i submersible pump. They differ in design and what they are best suited for.
Submersible pumps are usually shorter, compact units designed for submerged operation, often with a built-in float switch or a pressure machine. They are perfect where the water is clean or slightly polluted and the purpose is to water the garden or pump rainwater. You can find the full family in the category Submersible pumps and accessories.
Submersible pumps The 4-inch ones are slim and multi-stage, allowing them to achieve much higher pressures. This is a good choice when you need to deliver water from a Mauser over a longer distance, uphill, or to an installation that requires stable pressure (e.g. several sprinklers at the same time). The range is submersible pumps and well equipment, and specifically for reservoirs with a small water column depth, a subcategory is dedicated pumps for ring wells.
Specific pump models that fit Mauser
Multi IP 1000 AUTO – the convenience of a pressure machine
Ours submersible pump Multi IP 1000 AUTO is a model with a built-in automatic control. It responds to the opening and closing of the outlet valve, maintaining the pressure in the installation without the need for a separate hydrophore tank. Parameters: lifting height 40 m, capacity 100 l/min, power 1 kW, Power supply 230 V. AISI 304 stainless steel body, factory protection against dry running and cooling jacket, thanks to which the pump does not have to be completely submerged. Its diameter is 150 mm - it fits in a 155 mm flap, although tightly. This is a choice for someone who wants "I turn on the tap - water flows" without additional automation.
NEPTUN 50-60 and NEPTUN 40-110 – slim and universal
If easy installation is a priority, we recommend the NEPTUN series with a diameter of only 102 mm. NEPTUN 50-60 reaches a lifting height of 50 m with a capacity of 60 l/min (power 0.5 kW) - it is a "pressure" model, good where the water is to go higher or further. In turn NEPTUN 40-110 it has a flow rate of 110 l/min with a lifting distance of 40 m and a 1¼" connection, which makes it a good choice for quickly filling watering cans, barrels or pumping water. Both pumps have a body and shaft made of AISI 304 stainless steel and a 10 m long H07RN-F cable. Thanks to the 102 mm diameter, there is a lot of clearance around the body in the 155 mm flap.
SWQ 180 – small, light, for clean water
When you want lightness and low energy consumption, it is a good solution SWQ 180 pump. It has a housing diameter of 115 mm, weighs only 3.8 kg and has a power of 0.18 kW. Capacity of 70 l/min when lifting 5.5 m makes it a typical pump for pumping and powering small irrigation installations at low pressure. However, you must be aware of the limitation: when lifting only 5.5 m, SWQ 180 may not generate enough pressure to evenly supply the entire, longer drip line - the drip heads at the end of the long loop may receive significantly less water than those at the pump. For extensive drip irrigation, it is better to choose a model with a higher lift, e.g. NEPTUN 50-60 or a 4 OLA submersible pump. Leave SWQ 180 for short sections, pumping and hand watering. Important installation note: the impeller passage is only 2 mm, so SWQ 180 is intended only for clean or slightly polluted water - leaves, silt or fine sand may clog the impeller. In a Mauser, where the water is usually clear, this is rarely a problem, but if you collect rainwater from the roof, make sure you have a pre-filter.
4 OLA and 5 OLA deep well pumps – when you need pressure
Where submersible pump is not enough, here comes our 4-inch submersible pumps with cooling jacket, also ideal for ring wells and tanks with a shallow water column:
- 4 OLA 60 AUTO (0.45 kW) – lifting 58 m, capacity 55 l/min, diameter 124 mm, with automatic control and engine cooling jacket.
- 4 OLA 100 AUTO (0.8 kW) – lifting 58 m, capacity 90 l/min, diameter 124 mm. It combines high efficiency with the convenience of a machine.
- 4 OLA 60-60 INOX with float switch (0.8 kW) – lifting up to 72 m, capacity 60 l/min, diameter only 106 mm. The built-in float switch protects against dry running.
- 4 OLA 70-100 INOX with float switch (1.1 kW) – lifting 71 m, capacity 100 l/min, diameter 105 mm. A powerful model for demanding installations.
- 4 OLA 60-60 (1.0 kW) – lifting 60 m, capacity 60 l/min, diameter 100 mm, Connection 1¼".
- 5 OLA 80-150 (1.5 kW) – 5-inch version with a diameter of 134 mm: lifting 81 m and capacity 150 l/min. This is the most powerful pump described - it will work well when the Mauser serves as a buffer in a larger irrigation installation. Remember that at 134 mm the margin in the 155 mm flap is small.
All 4 OLA and 5 OLA models have an AISI 304 stainless steel structure, a 20 m power cable and operate in continuous mode, which is of real importance for a Mauser-type working tank.
Multi Dive 6-45 – note the lack of a cooling jacket
It is worth discussing separately Multi Dive 6-45 submersible pump float switch (0.75 kW). It achieves a capacity of 115 l/min and a lifting capacity of 45 m, and a built-in float switch protects it against dry running. It is also adapted to pump water containing chlorine. However, there is an important design difference here: Multi Dive 6-45 does not have a cooling jacket. The engine of such a pump releases heat directly into the surrounding water. Therefore, this model works best with a Mauser buried in the ground – the water in the buried tank is cooler and more thermally stable, the temperature difference between the engine and the liquid is smaller, and cooling is more effective. In a Mauser standing in the sun, where the water can become very hot and loses water quickly, the pump without a cooling jacket works in more difficult conditions. This is a real assembly tip, not marketing.
Should the Mauser be buried? And is it worth covering it with a cloth?
These are questions we get regularly, so let's clear up your doubts. Burying the Mauser it is not obligatory, but it brings specific benefits. The buried tank has cooler and more temperature-stable water, is protected from light (which limits the growth of algae) and does not disfigure the plot. This is also the optimal environment for pumps without a cooling jacket, such as the mentioned Multi Dive 6-45. The disadvantage is the time-consuming assembly and the need to protect the tank against ground pressure - the plastic IBC container is not designed to be fully loaded with soil, so make the decision to bury the Mauser consciously and with appropriate reinforcement.
If the tank stays on the surface, definitely it is worth covering the Mauser with a cloth or an opaque cover. Reducing light access is the easiest way to stop algae and keep the water in better condition, and a thermal shield reduces water heating up in summer. For the pump, this means cleaner fluid and gentler operating conditions.
Accessories that will extend the life of your Mauser pump
The pump itself is not everything. In an installation based on an IBC tank, it is worth considering several elements. Float switch protects against dry running when the water level in the pump drops - if the pump does not have it at the factory, you can choose it from the category float switches. Hydrophore controller or automat allows you to automate the operation of the pump without a built-in machine - you will find them in the categories drivers and hydrophore machines. If the installation is to maintain constant pressure, it will be helpful expansion tank, and for precise regulation of pump speed – devices from the category inverters (in our assortment, the inverter regulates the operating conditions of the water pump, it has nothing to do with the solar inverter). When Mauser water may be contaminated, consider: water filters protecting the rotor. It will also give you full control over switching pressure switch.
How to choose the hose diameter and calculate the parameters
When selecting a pump for a Mauser, do not forget about the capacity of the installation. A delivery hose that is too narrow will "stifle" even an efficient pump and generate pressure losses. Use our tool to quickly convert diameters pipe diameter converter, and a complete set of engineering tools - including the selection of cable cross-section and calculation of pressure losses - can be found on the website Dambat conversion factors. This really helps to avoid a situation in which a well-selected pump disappoints only because the installation cannot keep up with it.

Summary – which pump for Mauser should you choose?
The shortest cheat: if you want comfort and a pressure regulator, but the hatch may be tight - Multi IP 1000 AUTO. If easy installation and a slim body are important - NEPTUN 102 mm. For light tasks and clean water - SWQ 180. When you need high pressure - 4 OLA/5 OLA submersible pumps. And if the Mauser is dug into the ground - Multi Dive 6-45 z float switch, the lack of a cooling jacket does not prevent cooler, thermally stable water. However, always start with the diameter: 155 mm is a limit that cannot be circumvented.
