Description
MH 1100 – single-stage, 230 V surface-mounted screw pump
The IBO MH 1100 screw pump is a single-stage, self-priming surface-mounted screw pump designed for drawing and pumping technically clean, cold raw/untreated water from private water intakes, tanks, or wells before the water treatment process, as well as for boosting pressure in domestic, recreational, and agricultural systems. Its positive-displacement design (steel rotor/elastomer stator) also allows selected liquid fertilizers and process solutions to be pumped when the medium has low viscosity. The 1 m cable with a plug makes it easy to connect to a 230 V power supply.
Who is it for
- Homeowners and plot owners on elevated terrain – a lifting height of up to 130 m provides satisfactory pressure where the water intake is below the point of use.
- Farms and horticultural operations – the high operating pressure is suitable for supplying sprinklers, drip lines over long distances, and pumping selected liquid fertilizers in fertigation systems.
- Homeowners with water treatment systems – compatible with iron removal filters, manganese removal filters, water softeners, and carbon and mechanical filters, including during filter column backwashing.
- Users of small membrane systems – supply for selected reverse osmosis and nanofiltration systems (selection requires checking the pressure and flow required by the specific membrane).
- Installers of sprinkler and irrigation systems – ample capacity at medium and high pressures (38–20 l/min at 2–8 bar) makes it easier to select the pump for complex systems.
Applications
The MH 1100 screw pump is designed for drawing, pumping, and boosting the pressure of technically clean, cold raw/untreated water from private water intakes, dug and ring wells, and tanks before the water treatment process. The pump can be used in water supply systems for pressure-boosting stations, recreational plots, households, farms, and irrigation systems. If the water is to be used for drinking or domestic purposes, appropriate treatment and quality control at the point of use must be ensured. The pump does not treat water and does not confirm that the water is fit for human consumption.
- Pumping water over longer distances – farms, pastures, tanks, and plots located higher than the water intake.
- Supplying homes and installations on elevated ground where the water intake is below the point of use.
- High-pressure irrigation – drip lines over longer distances, sprinklers, nurseries, and orchards.
- Water treatment system supply (iron removal, manganese removal, water softeners, carbon and mechanical filters), including flushing of filter columns.
- Supply of selected small membrane systems and pumping of selected liquid fertilizers and process solutions in nozzle and fertigation systems.
Warning: the pump must not operate with the discharge valve closed. In installations where flow may be restricted or shut off, a bypass and a safety valve must be installed to protect the pump against excessive pressure buildup.
Tolerated operating media (other than water)
Water is the reference medium (100% concentration, viscosity approx. 1 mPa·s). In addition to water, the pump tolerates selected fertilizer and technical solutions, provided the specified concentrations are maintained and the viscosity is close to that of water (at 20°C). Before using a medium other than water, its chemical compatibility with the materials that come into contact with the medium must be verified – fertilizers and other chemically aggressive media may accelerate wear of the stator, rotor, and gland packing, which may then require periodic replacement.
Nitrogen and mineral fertilizer solutions
- Urea (solution): maximum concentration < 20%, viscosity approx. 1.3–1.6 mPa·s
- Calcium nitrate: maximum concentration < 15%, viscosity approx. 1.3–1.6 mPa·s
- Potassium nitrate (KNO₃): maximum concentration < 15%, viscosity approx. 1.2–1.5 mPa·s
- Monopotassium phosphate (MKP): maximum concentration < 10%, viscosity approx. 1.2–1.4 mPa·s
- Magnesium sulfate: maximum concentration < 10%, viscosity approx. 1.2–1.4 mPa·s
- Potassium sulfate: maximum concentration < 8%, viscosity approx. 1.2–1.4 mPa·s
- Compound NPK fertilizers: maximum concentration < 10%, viscosity > approx. 1.5 mPa·s
Glycols (process / antifreeze fluids)
- Ethylene glycol: maximum concentration < 20%, viscosity approx. 1.5–2.0 mPa·s
- Propylene glycol: maximum concentration < 20%, viscosity approx. 2.0–2.5 mPa·s
The pump is not intended for pumping
- Oils, fuels, petroleum-based fluids, oil emulsions, and other lubricating fluids.
- Organic solvents.
- Strong acids, including nitric, hydrochloric, and sulfuric acid.
- Strong bases and oxidizing agents, including sodium hypochlorite.
- Highly acidic or highly alkaline cleaning agents.
- Concentrated acidifying fertilizers based on strong acids.
- Media with a high chloride content.
- Liquids containing abrasive particles, such as sand, sludge, or sediment.
Features and technical specifications of the MH 1100 screw pump
A single-stage screw pump based on a positive-displacement design – unlike a typical centrifugal pump, its current draw increases as pressure rises and flow decreases. The pump housing and shaft are made of AISI 304 stainless steel, the discharge casing is made of cast iron, the rotor is made of AISI 304 stainless steel, the stator is made of NBR, and the mechanical seal is made of ceramic, graphite, and NBR. For systems in which the MH 1100 screw pump 230 V operates, we recommend installing the following protective devices: a bypass with pressure regulation and a safety valve, overcurrent protection selected for the motor's rated current, dry-running protection, and a pressure switch that shuts off the pump before the overload range is reached.

Frequently asked questions (FAQ) – MH 1100 screw surface pump
Is the MH 1100 screw pump suitable for a ring well?
Yes – the MH 1100 screw pump is a self-priming pump with a suction capacity of up to 8 m, suitable for dug and ring wells. Its positive-displacement design provides a head of up to 130 m, ensuring high pressure in domestic water systems and satisfactory performance over long pipeline runs. The pump is intended for raw/untreated water; when using the water for drinking purposes, it must be treated and its quality monitored at the point of use.
Will the MH 1100 screw pump perform well on a farm?
Yes—its high operating pressure enables water to be transported over long distances, which is useful for supplying pastures, orchards, and greenhouses, as well as low-pressure nozzles for cooling and humidification. The positive-displacement design also allows selected liquid fertilizers to be pumped in fertigation systems, provided that the concentration and viscosity are appropriately selected.
Can the MH 1100 screw pump convey liquid fertilizers and process solutions?
Yes, to a limited extent—the product sheet specifies the maximum recommended concentrations and approximate viscosity for selected media, such as urea solutions, calcium nitrate, potassium nitrate, magnesium sulfate, and glycols, with a viscosity similar to that of water (up to approximately 3 mPa·s). Fertilizers and other chemically aggressive media accelerate wear of the stator, rotor, and seal, so before using a medium other than water, we recommend checking its chemical compatibility with the pump materials.
Can the MH 1100 screw pump be used to increase pressure in water-supply systems?
The pump can be used to increase pressure in systems for drawing and discharging raw water, provided that the pressure entering the pump from the suction side does not exceed 2.5 bar. In this case, installing a pressure reducer and a check valve is recommended. Use in water-supply systems carrying water intended for human consumption is permitted only in accordance with the technical documentation for the given model. You can find dedicated accessories on our website.
Can the pump operate with the discharge valve closed?
No—the pump must not operate with the discharge-side valve completely closed. In systems where the flow may be restricted or shut off, a bypass and safety valve are required to protect the pump against excessive pressure buildup.
Where can I buy the MH 1100 screw pump for a well?
As the manufacturer, we do not sell directly. The MH 1100 screw pump is available from our trade partners, plumbing wholesalers, and authorized online distributors.
Where can the pump be serviced after the warranty expires?
Warranty and post-warranty service is provided by Dambat. IBO – 24 months (2 years) of the manufacturer's warranty.
