About booster pump ghv
The Lowara GHV series booster sets are fully automatic booster sets for water supply, water pressure increase and water transfer in condominiums, office buildings, hotels, public buildings, industries and other applications.
The GHV series is equipped with 1 to 4 e-SV vertical multistage pumps, each one fitted with a Hydrovar HVL variable frequency drive, pressure transmitters and a control panel, all mounted on a frame for easy installation. The GHV series is easy to program, designed for maximum energy efficiency and can communicate with a BMS system via Modbus or BACnet.
The GHV series is certified for use with potable water.
GHV booster sets are avaialble with up to 8 pumps. Other pump types and other special versions are available on request.
Lowara GHV series booster sets are designed to transfer and increase the pressure of water, in the following applications:
• Hospitals
• Schools
• Public buildings
• Industries
• Hotels
• Condominiums
• Sports facilities
• Mains water systems
GHV series booster sets are variable speed pumping stations with one to four e-SV series multistage vertical pumps.
Each pump is equipped with an HYDROVAR® frequency converter. This means that all the pumps are capable of variable speed operation. Special sets with up to 8 pumps are also available on request.
These types of systems improve the comfort of the end user, reducing noise emissions. Thanks to the gradual switching off of the pumps, “water hammer” is also reduced.
GHV10: The pump is connected to a delivery manifold by a non-return valve. Control panel is available as accessory.
GHV20, GHV20, GHV30, GHV40: The pumps are installed on a single base and connected to each other by means of suction and delivery pipes.
The pumps are connected to the manifolds by means of on-off valves and non-return valves.
The control panel is secured to the same base by means of a bracket
This type of drive is able to supply performance advantages:
• Progressive start with a voltage ramp having a duration adjustable within wide time limits.
• Limited current start with a value that can be set from 100% to 500% of the rated value.
• Descending voltage ramp having a duration adjustable within wide time limits.
• Voltage ramps at starting and stopping adaptable to particular operations (pumps).
• Low-speed operation, with reversible running direction, for specific applications.
• “Energy Saving” function with automatic reduction of the voltage/current in the case of a prolonged underload.
• Safety devices that can be calibrated to prevent overheating of the motor, over/under currents and over/under voltages.
• Safety devices that can be calibrated to prevent prolonged or too frequent starts.
• Possibility of by-pass operation after starting, keeping all the safety devices active
