Under Pressure - Use the Gauge to Get Relief
Any well-built hydraulic power unit (HPU) includes a system pressure gauge on the high pressure side. When this HPU gets paired with a hydraulically driven submersible pump, the readings on that gauge can both help the operator reach the best operating point (given current conditions) and assist in analyzing a problem situation when the submersible pump is not moving water.
Finding the Best Operating Point:
In many parts of life, more is better, but when it comes to operating an engine based hydraulic power unit, that is not the case. By using the pressure reading it is easy to find the sweet spot for any particular pumping situation. Specifically, the pressure shown on the gauge is an indication of the amount of work being done by the hydraulic motor on the pump head. The higher the pressure, the harder the motor is working. This working pressure profile can vary for different styles of pumps, but the one thing that is the same across the board is this…when adjusting engine rpm the operator will see system pressure rising and until it stops. When the needle stops moving, it means that given the current set up, the system is at its most efficient point. Attempting to increase engine speed in an effort to get more submersible pump flow will only result in burning more fuel; it will not change the gpm output of the head. Of course, as conditions change, that ideal point will change too, so further adjustments will be required to stay at the best spot. By educating your customers and staff about this pressure point, it becomes a win, win, as fuel costs can be cut, wear and tear on engines is reduced and the environmental impact of the fuel burn is minimized.

Product of the month:
S4SCR
Hydra-Tech's S4SCR, 4 inch hydraulic submersible screw pump, is ideal for pumping high viscosity liquids such as crude oil, latex, molasses and refinery wastes. This pump uses a positive displacement screw impeller. When pumping lighter materials, the impeller acts as a centrifugal type providing high volume outputs. Combining this pump with our HT16 to HT35 power units, the S4SCR is capable of flows up to 900 GPM. The safe and variable speed hydraulic drive can be used where electric power is hazardous or impractical.
New Employee

After a record sales year in 2018 Hydra-Tech Pumps has added a new employee in their sales & marketing department to help them as they continue to grow. Mike Screenock joined Hydra-Tech Pumps on March 11 th in a Sales and Customer Support Role. He has been involved in outside and even route sales roles as well as production roles in prior jobs. For Hydra-Tech he will be involved with inside sales, marketing, customer service and trade shows. This hire is driven by our continued growth and the need to continue to match our growth with internal support for our customers. 
Mike is a family man with a wife and 3 children all under the age of 5. When Mike is not chasing his children around, he enjoys buying and selling items online. Please help us welcome Mike to Hydra-Tech Pumps the next time you call and get him on the phone.
