Electronic Flow Control Is More Accurate and Reliable

Conventional metering pumps rely on manual stroke adjustment or expensive actuators to change flow. This can result in pumping inaccuracies, lost motion, operator error, and a greater chance of leakage. Hydra-Cell uses Variable Frequency Drive (VFD) electronic flow adjustment to maintain greater accuracy throughout the turndown range. It meets or exceeds API 675 performance standards while eliminating lost motion and a potential leak path. Compared to many conventional metering pumps, electronic flow control of Hydra-Cell also reduces the chance of operator error.

Accurate Metering with Linear, Virtually Pulse-free Flow

Conventional metering pumps produce pulsing, surging flow and require large pulsation dampeners that add cost and complexity to a metering system. This inherent problem with conventional metering pumps creates a greater strain on the system and more wear and tear on the pump. Hydra-Cell Metering Solutions pumps (except the P100 and S Series) feature a multiple-diaphragm design that minimizes pulsations. This produces smooth, linear, virtually pulse-free flow without the need for expensive pulsation dampeners.

Reduced Pulsations Improve Operation by:

• Reducing pipe strain
• Enhancing operating safety
• Minimizing maintenance
• Reducing friction and acceleration losses
• Eliminating the need for pulsation dampeners
• Lowering system acquisition costs
• Providing accurate metering and injecting with linear, constant flow and eliminates the “slugs”
common to conventional metering pumps

Greater Choice of Materials Enhances Capability and Versatility

A choice of diaphragm, check valve, and liquid end materials enable Hydra-Cell Metering Solutions pumps to operate over a wider range of processing applications than conventional metering pumps. In addition, special materials such as PVDF and Hastelloy C are available in standard Hydra-Cell packages. Hydra-Cell is lower in cost compared to conventional metering pumps that have substantial price adders for exotic liquid end materials.

Manifolds:

Manifolds for Hydra-Cell Metering Solutions pumps are available in metallic and non-metallic materials to suit your process application. They are easy to replace and interchangeable to accommodate different fluids processed by the same pump. Special manifolds are also available that offer 2:1 ratio pumping or the simultaneous pumping of three dissimilar fluids.

Valves:

Hydra-Cell Metering Solutions valve assemblies (seats, valves, springs, and retainers) are available in a variety of materials to suit your process application.

Diaphragms and O-rings:

Conventional metering pumps typically offer only PTFE diaphragms. When subjected to flex stresses, PTFE diaphragms do not have a “memory” like elastomeric diaphragms and will require more frequent and costly replacement due to stresses on the material. In addition, if fluid and process temperatures are low, and the PTFE diaphragm is cold, it can stiffen and cause irregularities in the output and a drop inflow. Hydra-Cell offers PTFE diaphragms, as well as many other elastomeric material choices that may be more cost-effective or better suited to the application.
