Hydraulic Power Units

The electric motors are sourced from trusted European suppliers. High efficiency, as per the IE3 classification, keeps energy consumption low.

The adapter that secures the electric motor and hydraulic pump to the cover is made of cast and machined aluminum to ensure a secure mounting and a long service life.

The pump is submerged in the oil to reduce noise levels and minimize the risk of cavitation. This solution also reduces the need for piping components and the risk of leaks. To further lower noise levels, screw-type hydraulic pumps are used.

The cover has brackets for wall mounting but can also be attached to a stand for floor mounting. Virtually all hydraulic components are mounted inside the cover, which simplifies component replacement and maintenance.

The oil reservoir is secured to the lid with an eccentric lock, which simplifies installation, maintenance, and cleaning.

The sight glass makes it easy to check the oil level in the reservoir and can be equipped with a thermometer to also read the temperature of the hydraulic oil.

The level and temperature monitor electronically monitors the system and shuts it down if the oil level is too low or the temperature is too high.

Lalmek's pressure-reversing directional valve has only a single adjustment knob that sets the pressure at which the hydraulic cylinder reverses direction. During repeated back-and-forth motion, no control system is needed, since the reversal occurs mechanically using the pressure in the system.

Valve blocks are used to mount valves and other equipment on the unit. The individual blocks are mounted on top of one another and are available both with and without a built-in pressure relief valve with a graduated adjustment scale.

The filter pressure gauge measures the oil pressure in the return filter and indicates well in advance when it is time to replace the filter.

The return filter cleans the hydraulic oil that is returned to the unit and is essential for ensuring a long service life for both the hydraulic oil and the system's components.

The bypass valve protects the filter from damage if unexpected pressure surges occur in the system. The return line directs the returned oil down into the reservoir below the oil level to prevent air bubbles from being drawn into the system via the hydraulic pump.

The filler cap has a built-in breather filter that ventilates the oil reservoir while maintaining its cleanliness—no dirt can get in.

The drain plug is located at the bottom of the oil reservoir and makes it easier to drain the oil during an oil change.

The oil reservoir is made of sheet metal to help cool the hydraulic oil. It is secured to the cover with an eccentric lock.

The suction filter is located just above the bottom of the tank and is essential for ensuring a long service life for the hydraulic pump and other components. The suction tube is available in several lengths and can be angled to position the suction filter correctly.

The shaft coupling is installed between the motor and the pump and ensures a smooth start and stop. The flexible coupling effectively reduces vibrations and noise in the unit.

The rubber seal between the oil reservoir and the cap prevents external contaminants from entering the oil reservoir.

Standard adapters are mounted in the valve block for easy connection of hoses or pipes to the rest of the system.

The pressure hose connects the pump to the valve blocks.

All units are marked with a unique serial number to facilitate technical support and the supply of replacement parts.
