ZUWA Impeller Pump ACOSTAR

IMPELLER PUMP MADE OF PTFE FOR THE CHEMICAL SECTOR
The ACOSTAR impeller pump is the optimum pump for the chemical sector thanks to the use of PTFE, high-quality shaft seals and impellers made of FPM/FKM (Viton®) or EPDM. It is suitable for both oxidized, diluted, as well as mixed acids. Dry-running of the pump is prevented by the use of an effective dry-running protector (only for 230/400V). Various motor versions are available (230V, 400V, 12V, 24V; 1,400 rpm, 2,800 rpm; 50Hz, 60Hz). Using a frequency converter (optional) allows adjustment of the pump’s speed and direction of rotation.
The pump shaft of the ACOSTAR is made of Hastelloy® C-22. This material offers good resistance to media such as, sulfuric acid, phosphoric acid, nitric acid, chlorine gas, acid mixtures containing sulfuric acid, and oxidizing acids containing chloride ions. In the presence of strong oxidizing agents such as iron(III) and copper(II) chlorides, chlor, formic acid, acetic acid, seawater and other salt solutions, the use of this material is recommended after clarification of the environmental conditions. A special feature of this alloy is its high resistance to crevice, pitting and stress corrosion cracking at elevated temperatures under oxidizing and reducing conditions.
Star handles for quick and easy impeller replacement and ceramic side discs to protect the pump covers are installed as standard. The newly developed bellhousing allows the pump to be easily separated from the motor to perform service work.
