| 摘要 | The pump includes a pumping chamber within a sealed internal chamber, a pump inlet connected to the pumping chamber, a pump outlet connected to the pumping chamber, and a rotational pumping element configured to pump the corrosive fluid from the pump inlet to the pump outlet. The rotational pumping element is within the pumping chamber. The pump includes a drive shaft for driving the rotational pumping element. The drive shaft is completely within the sealed internal chamber. The drive shaft is configured for magnetically coupling to an external motor. A pump housing forms the sealed internal chamber. The rotational element, the pumping chamber, and the pump housing are formed from any one a conductive plastic, a non-conducting plastic with conducting particles, a semi-conducing ceramic, and combinations thereof. The drive shaft is formed from the semi-conducting ceramic. | ||||||
