WMTA alloy regenerative turbine seal-less mag-drive pumps (superseding the WMDAT) are ideally suited for low flow/High Head Applications. All WMTA pumps are equipped with zero leakage magnetic couplings to meet the latest toxic emissions regulations. The absence of mechanical seals or packing glands eliminates costly pump maintenance, lost production time and process contamination. The WMTA pumps are able to pump liquids containing up to 20% entrained gas. The WMTA pumps are suitable for thick non-lubricating liquids and/or high differential pressures.
