Lower Energy Consumption
The ESP pump only uses electricity when the nozzle is on and the machine is cutting.
While the table is being loaded/unloaded or traversing from hole to hole or end to end
the pump pulls 0.2 Amps. All other technology on the market uses power from the time
you start the machine until you shut it off.
The ESP pump is also 90% efficient compared to hydraulic intensifiers which are 60 to
65% efficient. That means you get 90% of the energy you pay for out of the cutting head
which is a major benefit.
Lower Water Usage
Water is used for two functions on a waterjet. 1) Cooling of the pump. 2) Cutting as either the cutting tool or the carrier for the abrasive.
Because the cooling system is extremely efficient, the ESP pump uses about 25% less water than other pumps on the market. The water used for cutting is fairly similar for most waterjet cutting systems. It is based on a combination of HP and pressure. More HP produces more water volume and the higher the pressure, the less water you consume. This is normally from 0.8 GPM to 2 GPM.
Note: Some competitor machines do not stop using water when you are loading/ unloading the table or traversing from hole to hole. They divert the water down the drain which wastes water and the life of your seal.
Lower Deadhead Pressure Spikes
Deadhead pressure spikes occur every time a cutting nozzle abruptly closes and the pump either stops or the water is diverted. At that moment, most systems experience a massive pressure spike of between 3,500 and 5,000 PSI which causes extensive fatigue on the high pressure components. This results in the affected lines, elbows, “T”s, swivels and on/off valves needing to be replaced frequently and the unplanned down time can be untimely. The more pierces your job requires the more stress on all the high pressure components.
However, the Techni ESP pump is controlled by a servo motor and ball screw. This extremely accurate system enables the pump to stop more precisely, reducing the deadhead pressure spike to an acceptable level. The ESP single pump spikes at around 300 to 500 PSI and the dual ESP pump at about 100 to 150 PSI. This greatly reduced pressure level is easier on the components so they don't need to be replaced as often, reducing costs and unexpected downtime.
More Time Between Rebuilds
Pump rebuilds happen every 250 to 1,000 hours depending on a number of factors like water quality, water temperature, water pressure, etc. The ESP requires rebuilds less frequently, every 500 to 1,000 hours of nozzle-on time.
Pumps in the industry range from one to four hours to rebuild. The ESP pump can be rebuilt in less than four minutes.
Advanced Self Diagnostics
Most pumps rely on the experience and observance of the operator to hopefully prevent the machine they are running from having unexpected failures.
Techni's unique Advanced Self Diagnostics system is derived from nearly thirty years experience. It ensures the ESP pump monitors all pump functions, temperatures and flow rates and advises the operator of any condition that, if not addressed, will cause a unexpected down time.
The operator then has the option to continue by bypassing the alarm. However, on the third alarm, they need to sign in on the control panel, assuming responsibility of the potential component failure.
The Techni ESP pump is easily integrated into any machine or robotic/automated system.
The pump comes standard with a pressure inducer to know when the cutting head is either open or closed. No interface between the pump and machine is required as the pump know precisely when to start and stop.
Less cost of Operation.
The Techni ESP pump cost approximate 1/3 the cost per hour to operate over other pumps in the industry.
After many years of integrating other pumps to their machines and robotic systems, Techni was aware of the shortcomings of the technology available at the time. They decided to design and build their own pump that would have the following features and benefits and in 2008, Techni introduced the first ESP pump.
Now, in 2016, Techni is proud to introduce it’s newest model, the G4 Electric Servo Pump (ESP), defining the future of waterjet cutting. This unit provides even lower maintenance costs and predictive maintenance intelligence through Advanced Diagnostics. The G4 ESP offers cutting edge technology and innovative features with a robust design and engineered elegance like no other.
Noise Reduction The pump runs at 68 dB which is the lowest in the industry.
