Domestic waterworks MHI 1300 inox / 100L

Product detailed description

This pump is suitable for a variety of installations, including single-family homes, small apartment blocks, and commercial premises such as workshops and retail units. It supports systems requiring stable water pressure and flow, particularly where the mains supply is insufficient or uneven. Installers typically encounter this unit in applications involving secondary water distribution, such as filling cisterns, supporting irrigation, or feeding hot and cold water lines in multi-storey buildings.

The compact design allows for installation in utility rooms, basements, or dedicated mechanical spaces. The pump operates within standard electrical networks and can be integrated with control systems for automated operation. Due to its stainless steel construction, it is well suited for environments with fluctuating temperatures or where corrosion resistance is required.

The maximum flow rate of 100 L/min determines its suitability for systems with moderate demand, while the head of 55 m ensures it can overcome elevation differences or pressure losses in longer pipe runs. The 230 V power requirement aligns with standard European electrical systems. The dimensions and weight should be considered during planning to ensure sufficient space for installation and access for maintenance.Installation and connection During installation, the pump should be mounted on a stable, vibration-dampening base to reduce noise transmission. The inlet and outlet connections require appropriate pipe fittings to prevent leakage and ensure secure coupling. The 1 m length of the incoming cable should be routed to a dedicated circuit with proper overcurrent protection. Prior to commissioning, the installer must verify the correct phase rotation and insulation resistance. Common errors include incorrect pipe sizing, which can cause cavitation, and failure to install a non-return valve, which may lead to backflow and damage.Compatibility and accessories This pump is compatible with standard copper or PPR piping systems and can be used with pressure switches, flow meters, and control panels for automated operation. To complete the system, additional components such as expansion vessels, pressure tanks, and filters may be required. These should be selected based on the specific application and system requirements.Technical background for designers The pump operates on a centrifugal principle, using an impeller to increase the kinetic energy of the water and convert it into pressure. The stainless steel casing provides resistance to corrosion and ensures long-term reliability. The impeller and shaft assembly are precision-machined to maintain hydraulic efficiency. The integration into the system depends on the layout and demand profile; factors such as pipe friction, elevation changes, and the number of fixtures affect the overall performance. Regular monitoring of flow and pressure can help identify potential issues early.Service and operation Routine checks should include verifying the tightness of all connections, inspecting the condition of seals and gaskets, and ensuring the electrical connections remain secure. The pump should be tested periodically under load to confirm it maintains the specified flow and pressure. No scheduled service intervals are provided in the technical data, but any signs of unusual noise, vibration, or reduced performance should prompt further investigation.Frequently asked questions

Can the pump be installed in a vertical position?
Yes, the pump can be mounted vertically, provided the base is stable and the inlet is positioned correctly to avoid air entrapment.

Is a pressure tank required for operation?
A pressure tank is recommended to stabilise pressure fluctuations and reduce the frequency of pump cycling.

Can the pump handle hot water?
The pump is suitable for cold water applications only. Hot water may affect the sealing materials and reduce service life.

What is the maximum allowable ambient temperature for operation?
According to the manufacturer’s technical data sheet, the pump is designed for normal ambient conditions. Extreme temperatures may require additional insulation or ventilation.
