Emotron applications · Pumping systems
Industrial pump automation and control
Pumping systems account for up to 20 % of electrical energy consumption in industry and utilities, and many operate with no adaptive control. As the official Emotron distributor in Central America, E3 Solutions designs and installs pump control solutions in Guatemala: FDU variable frequency drives, TSA softstarters and M20 shaft power monitors that adapt operation to actual demand, eliminate water hammer and protect the equipment.
The challenge: efficiency, protection and continuity in pumping
A pump that starts direct-on-line and runs at constant speed wastes energy every time demand falls, and subjects the pipework to pressure spikes each time it starts or stops — the phenomenon known as water hammer. Without protection, hot water or loss of flow empties the impeller and the pump runs dry until it burns out. In multi-pump systems, manual control of the number of units in service causes pressure swings that affect the downstream process.
- High energy consumption from running at full speed regardless of actual demand
- Water hammer on start and stop: damages pipes, valves and seals
- Dry-running risk when the well level or suction pressure drops
- Pressure swings in multi-pump systems managed manually
The Emotron solution
The Emotron solution
Emotron FDU variable frequency drives continuously adjust pump speed to the system's actual demand. Process parameters are set directly in m³/s or bar, with no complex programming. A single unit can monitor and control up to seven pumps without an external PLC, starting or stopping units according to load. The sleep function stops the motor when pressure no longer requires work, eliminating standby consumption. The TSA softstarter performs linear stops that suppress water hammer without costly motor-operated valves. And the M20 shaft power monitor uses the motor itself as a sensor to detect dry running and overload across the entire speed range, before damage occurs.
Recommended equipment
Recommended Emotron products for pumps
Equipment selection depends on pump type, process and the level of control required. These are the options we specify most often in pumping projects.
Emotron FDU
The FDU drive adapts pump speed to actual demand, includes a sleep function that stops the motor when no pressure is needed, and controls up to seven pumps from a single unit without an external PLC.

Emotron TSA
The TSA softstarter performs linear, controlled stops that eliminate water hammer without costly motor-operated valves, significantly reducing stress on the pipework.
View product
Emotron M20
The M20 shaft power monitor detects dry running and overload using the motor itself as a sensor, with no external instrumentation, protecting the pump across the entire speed range.

Key features of pump control
The functions that make Emotron drives the most complete solution for demanding pumping systems.
Water hammer elimination
The linear stops of the drive or softstarter reduce pressure gradually, preventing the hydraulic impact that would damage pipes, valves and mechanical seals.
Energy saving with sleep function
When system pressure holds without the need to pump, the drive automatically stops the motor and restarts it when a pressure drop is detected, eliminating standby consumption.
Dry-running protection
The M20 monitor tracks shaft power throughout the operating cycle. An unexpected load drop triggers the alarm and stops the pump before the impeller is damaged.
Multi-pump control without external PLC
A single FDU drive can manage up to seven pumps, starting or stopping units according to demand, with parameters configured in process units such as bar or m³/s.
