Abrasive tile coatings
Published: 25 November, 2016
WANNER says its Hydra-Cell seal-less pumps, have solved a pump seal wear problem for a major producer of acoustic panels. When pumping abrasive coatings, pumps with dynamic seals can eventually wear and leak, performance accuracy deteriorates and maintenance downtime for seal replacement can prove expensive as the Corporation found to its cost.
Wanner says replacing the pneumatic, single plunger pumps with Hydra-Cell G10 and G25 seal-less pumps not only solved the leak problem but also greatly improved the control over spray patterns and coating thickness and with no dynamic seals to wear, the Hydra-Cell pumps are able to pump the abrasive coating material reliably and require minimal maintenance. Having multiple, hydraulically balanced diaphragms in a single pump head, the Hydra-Cell pumps produce a smooth pulseless flow without the need for pulsation dampeners.

WANNER INTERNATIONAL says Hydra-Cell pumps are increasingly being specified and retrofitted in pipeline sampling installations used for analysis during oil transfer - data that can be essential for identification or quality measurement purposes.
WANNER says its new, seal-less, hydraulically balanced diaphragm pump offers flow rates up to 366 lpm at pressures up to 103 bar.
WANNER INTERNATIONAL says its Hydra-Cell Metering and Dosing solutions range includes variants with integrated variable speed drives and says the innovative design combines an AC induction motor with a Variable Frequency Drive (VFD inverter) mounted on the motor.
WANNER INTERNATIONAL reports it has introduced a range of Hydra-Cell, ATEX approved Dosing Performance Pumps with precise mechanical variator control, all mounted on a substantial stainless steel base plate.
AXFLOW has announced it has extended its range of positive displacement pumps with the introduction of the LB suite of elastomer coated rotary lobe pumps for flows of between 5m³/hr to 130m³/hr. AxFlow says the LB pump has been designed from scratch following an assessment of products currently on the market with a view to producing a process quality pump, positioned above the more agricultural designs yet without attracting the high costs of high end products.
