Metering Syringe Pumps
As a long respected syringe pump manufacturer, PDC Machines designs rugged metering syringe pumps for an extremely accurate injection of fluids irrespective of viscosity into a system at a consistent flow and constant output pressure. For these positive displacement pumps, we design both single and double barrel syringe pump setups for batch and continuous flow operations. In a continuous flow operation, one barrel is discharging fluid, while the other retracts, pressurizes to set pressure and gets ready for transfer.
Standard features include:
- Flow Rates: Programmable syringe pumps have flow rate range from (0.004 mL/min to 4 mL/min) to (0.4 mL/min to 400 mL/min)
- Flow Characteristics: Pulse-less, linear output flow
- Accuracy and repeatability of flow +/-0.05% of set point
- High Discharge Pressures: Up to 60,000 psi (4,100 bar)
- Pump Barrel Temperature: Up to 450 °F (232 °C)
- Large Barrel Capacities: 125 cc to 1500 cc
- Simplex (single) Barrel Design: Batch operation
- Duplex (two) Barrel Design: Continuous operation
- Plunger & Barrel Materials of construction: Available in Stainless Steel, Hastelloys, Nickel, Titanium for process compatibility
- Stationary Seals: Double, self-energizing, adjustable with leak port for collection of leaks for mass balance
- Packing: Standard is graphite filled teflon (PTFE), other packing materials are optional
- Drive Motors: Servo, Inverter Duty
Controls
PLC based and relay logic user-friendly programmable syringe pump controls make it easy for the operator to set system parameters such as pressure and flow rates. Customer has option of local control/ display panel mounted on skid or remotely linked to DCS interface inputs or PC based MMI.
For simplex designs, control/display panel is supplied loose for customer local or remote mounting.
PDC Machines’ high pressure syringe pumps can be installed in hazardous areas
PDC Machines’ syringe pumps can be located in Class 1, Divisions 1& 2, Groups B, C, D:
All Components on pump skid are wired to a local Nema 7,9 junction box.
Pump controller (enclosed in a Nema 4,12 junction box) is supplied loose for mounting in a non-classified area, or pump controller can be mounted locally if purged.
Inter-connecting wiring is done by customer after skid and pump controller are installed.
Optional features
- High – speed reverse for fast barrel filling
- Electrically heated barrel (s)
- Jacketed barrels for heating/cooling by customer
Electrical requirements
Per customer specifications.
Continuous feed syringe pumps for chemical, reaction, catalysis and liquid chromatography applications
PDC Machines’ pulse-less pumps are continuous feed pumps that are ideal for use in laboratories, pilot plants and industrial production applications when there is a need for:
- Consistent & extremely accurate pulse-less flow
- Constant output pressure
- Rugged & continuous duty operation
