Compact in size, the pumps have a seal-less design that is said to eliminates leaks, hazards and the expense associated with replacing dynamic rotary seals and packing. Wanner says the pumps can operate with a closed or blocked suction line and run dry indefinitely without damage, eliminating downtime and associated repair costs.

API 674 configurations of Hydra-Cell pumps are also available as are versions with ATEX Cat 2 Zone 1 & Cat 3 Zone compliance.

The Hydra-Cell metering and dosing range will also be featured, with focus on the electronic and mechanical adjustment control options now available.

Exceeding the performance requirements of API 675 in terms of repeatability, linearity and steady state accuracy, the Hydra-Cell with multiple diaphragms in a single pump head configuration generates virtually pulse-less flow, removing the need for pulsation dampeners in most applications.

The special high efficiency multi-diaphragm design is claimed to handle abrasives with less wear than gear, screw or plunger pumps. The pumps are said to have low energy requirements and minimal maintenance needs.
