Frequently Asked Questions
Here is our FAQ, if you need more information or have a question not listed here, please contact us, we will be happy to inform you.
We perform all prototype design/construction from our California R&D facility. Prototype design/fabrication range from 2-15 days. Prices vary depending on complexity.
Custom is sometimes misinterpreted to mean expensive. This is not the case. Designing a pump for a specific application ensures optimum performance, a small package size, minimum power consumption and long life—resulting in space savings, low power consumption and a lower installed cost.
DPP designs and manufactures custom pumps to fulfill your OEM equipment requirements.
DPP tests at your operating conditions. This ensures that the pump performs to expectation before you validate in your equipment. We are also capable of conducting long-term endurance testing, environmental and chemical compatibility testing.
No. Every pump is designed and tailored to our customer’s exact needs. We have a minimum volume requirement of 100 pieces/year.
The customer provides DPP with the performance requirements via an Application Data Sheet (ADS). DPP uses this information to size the pump, design the interfaces and set up the test/validation program.
This depends on the application (flows, pressures, fluid cleanliness, duty-cycle, etc…) Our engineering team is experienced in life-enhancing designs and takes this into consideration with each application. In many applications, our pumps out last the life of the instrument.
The wetted materials are chosen to be compatible with your fluids. DPP uses inert materials wherever possible to resist a wider range of fluids.
A magnetic coupling is used in the gear pumps to transmit torque from the motor to the pump without a shaft seal, ensuring no leaks and easier cleaning.
DPP gear pumps are typically fitted with BLDC, conventional DC and AC motors. DPP metering pumps are usually attached to either stepper or BLDC servo motors (to maintain dispense accuracy).
A metering pump is a positive displacement pump that accurately moves small fluid volumes. DPP metering pumps use a ceramic piston with a variable displacement feature to “dial in” exact flow rates.
A gear pump contains two-or-more gears that rotate, carrying small pockets of fluid between the gear teeth. These pockets are squeezed as the gears mesh, forcing the fluid out.
Our manufacturing is performed at our facility in Switzerland to the highest Swiss quality and workmanship. All design, development and prototyping is performed at our R&D facility in California.
Our manufacturing is performed to ISO 9001:2015. Further certifications for environmental, sanitary, and medical standards are available on a case-by-case basis—consult our factory for details.
In general, the pumps last so long servicing is not required. If performance does drop, it is more cost effective to replace the pump head than to service it.
