High Pressure Pumps

High Pressure Pumps

Positive Displacement Syringe Pumps from Fluitron

Series SP Motor Driven Syringe Pumps

The Fluitron SP Series high-pressure syringe pumps are motor-driven, positive displacement pumps designed specifically for the precise injection of catalysts and other fluids into high-pressure systems.

Our syringe pumps for high pressure systems are designed with a slow-moving plunger moving through a relatively large “barrel”. Controlling the speed of the motor accurately controls the plunger speed and therefore, the flow rate. Since the pump does not reciprocate, there is a continuous, pulseless flow.

Another advantage of the SP Series syringe pump is that there are no check valves to malfunction, “miss a beat”, or respond differently to various flow conditions or fluid properties.

The SP series syringe pumps are available in various flow ranges, volumes, and pressures. For applications requiring continuous, pulseless flow over long periods of time, two pumps can be configured in a duplex arrangement.

Series MP Hand Pumps

The Fluitron MP hand pumps cover a pressure range of 15,000 to 150,000 psi in 5 models. They are easy to operate and maintain and are suitable for use on many fluids.

The linkage in the MP pumps is simple, and has a high mechanical advantage, permitting the development of high pressure with reasonable effort. The basic design results in a compact unit of low weight resulting in a truly portable high pressure pump.

Materials used in these pumps have been chosen to permit use with tap or distilled water; alcohol; synthetic oil; etc.

Plungers in the 100,000 and 150,000 psi pumps are Tungsten Carbide, hand finished for wear resistance and low leakage. Plungers on other pumps can be supplied in 17-4 SS, 316 SS, etc.

The check valves are springless, ball type, operating in cages providing the necessary guiding and lift required for proper operation. The check valves are vertical so that all air is purged and priming is assured in a few strokes.

Pressures300 to 100,000 psi
Volume7 cc to 1 L
Flow Measurement1 cc/hr to 10,000 cc/hr
Continuous OperationStandard single barrel syringe pumps are designed for batch type operations.
Depending on your application, Fluitron’s syringe pumps can be configured for near pulseless flow and continuous operation. The continuous pump features a double barrel design that utilizes two pumps running off a single motor.
The pumps would be set up 180 degrees out of phase so when one pump is discharging, the other pump is filling.
This option would only have a short time without any flow when the pump stops and reverses
For pulseless flow, we design a complete pumping system with a single PLC control system. This system would at all times have one barrel operating and one barrel recharging and then building pressure. When the first barrel is near the end of it’s stroke it slows down and the second barrel speeds up. This would allow for a relatively pulseless transition between the two barrels.
Control SystemsMicroprocessor or PLC controls available for Flow and/or Pressure control
JacketsElectric heat or vapor type jacket for the barrel for heating or cooling
Special MaterialsA wide variety of higher alloys are available for corrosive service
Other OptionsPiping – includes valves, fittings, tubing as required
Pressure Gauge
Safety Shield
