Manufacturer: Vindum Engineering, Inc.

Model Number: VP-Series

Vindum VP-Series pumps are dual-piston high-pressure metering pumps that deliver ultra-precise, pulse-free, continuous flow in either constant-pressure or constant-rate modes, at up to 25,000 psi. High-temperature versions allow wetted parts of the pump to be heated to 320°F (160°C). Leading-edge design, compact size, and attractive pricing make these metering pumps perfect for a wide range of applications.

Features include:

  • Pulse-free continuous flow standard (pressure or rate modes)
  • Flow rate range: 0.1µL/min—97ml/min (varies by model)
  • Extreme pressure capability: 0 – 25,000 psi (varies by model)
  • 13 modes: rate or pressure deliver, receive, bi-directional
  • Advanced pump-control software included (PC-based)
  • Several control/communication options (see Control Options tab)
  • Low maintenance design, easy to clean
  • Ultra-compact footprint (19”H x 6”W x 9”D)

VP-Series Pump Applications:

  • Energy Coreflood and PVT Experiments
  • Chemical or Biofuels Pilot Plant or Process Testing
  • Continuous Additive Injection
  • Processes involving corrosive fluids and/or high-temp fluid injection

VP-Series High-Temperature Pumps

We offer two versions of our VP-Series pumps for high-temperature service (to 160°C/ 320°F):

  • Heating jacket with controller
  • Elongated pump for inserting pump cylinders into oven

The VP-3K, VP-6K, and VP-12K pumps can be ordered in either configuration. For more information and specifications, please contact Vindum Engineering using the REQUEST A QUOTE button above.

VPware is a PC-based software application, developed by Vindum Engineering, to operate the VP-Series pumps. It is included (free) with the purchase of any VP-Series pump. VPware is the most advanced pump-control software of its kind. It has an intuitive interface that is friendly to new pump users while offering capabilities to meet the demands of experienced operators. The combination of VPware and VP-Series pumps delivers excellent performance, extensive features, and ease-of-operation to meet any user’s requirements. We are also happy to add new features based on customer’s needs.

VPware: Loaded with features

  • Thirteen Pump Modes, , including pulse-free constant-pressure or constant-rate modes (deliver, receive, or bi-directional). Delta-Pressure and Recirculation (for core flood experiments) are also available.
  • Volume or Time Dispense: : Precise pumping by fluid volume or time.
  • Ramping Sequences: Build multi-step ramp sequences (ie, change pressure or rate as function of time or volume pumped) are easy to build and use.
  • Auto-Prime Feature: Automatically fills pump with fluid and verifies that residual air is eliminated from cylinders.
  • Pressure or Rate Following: Pump #2 follows rate or pressure of Pump #1, either as percentage or differential. Run ramping sequence on Pump #1 and Pump #2 will track its rate or pressure path automatically.
  • Pump Group (Rate modes): Multiple pumps operate together to deliver/receive a combined fluid rate, with individual pump rates set as percentage or proportion of the total rate, or individual values.
  • Data acquisition module: External device with analog inputs and digital controls.

VPware: Informative & Intuitive

  • Intuitive pump configuration, operation, and status screens.
  • Graphs that are easy to create, save, and view in real-time.
  • Data log any/all pump parameters at up to 50 milliseconds intervals.
  • Create pump schedules (rate or pressure) quickly and easily.
  • Informative warning and error messages provide guidance and feedback.
  • Error analysis records pump commands and data for easy troubleshooting.
  • Control 16 pump simultaneously or run multiple VPware sessions concurrently.

There are several control system options available for the VP-Series pumps. These are summarized in the table below. If you have any questions or need another control method, please contact us at

The hardware-level control format for VP-Series pumps is serial/binary (non-ASCII) with cyclic redundancy check (CRC), using byte string command-response protocol. All communications from the pump are in the form of responses to commands; the pump does not send any unsolicited messages. This communication format has been adopted because of the efficiency/speed that it offers compared to other forms of communication (e.g., ASCII). A .NET DLL (Dynamically Linked Library) is layered over the serial code to provide software developers with a simple PC-based API (Application Programming Interface) for pump control. VPware and the VPware LabVIEW Driver use this DLL. Beyond PC-based controls, the pumps also have an additional port that provides limited analog/digital pump control. For pump control with Fieldbus and Industrial Ethernet systems, we offer configuration for HMS Anybus® Communicator™, a protocol converter device that enables our pumps to be used in all major Fieldbus/IE systems.

Pumping fluids with dissolved salts (e.g., brines) can result salt precipitation on the pump’s pistons, which can cause premature wear on the piston seals. To prevent this, we have developed a wash kit that continually washes the pistons with distilled water. This kit can be easily installed at any time. The kit includes all the items shown in the photos. For more information, please contact Vindum Engineering using the REQUEST A QUOTE button above.

VP-Series Metering Pump Front View

Vindum Engineering offers a “loaner pump” program, which gives prospective customers the opportunity to try a VP-Series pump in their facility for a period of time (typically 4-8 weeks). If interested, please fill out the form below with your information.

While we cannot accommodate every loaner pump request or commit to having a loaner pump available at all times, we are committed to offering new customers the opportunity to work with our pumps so that they can experience their performance first-hand.
