Design Features

ISO design is in accordance with international standards of ISO2858/5199, which means ISO Series pumps are interchangeable with other similar pumps, conforming to the same standards. This ensures a robust, long lasting, high performing product consumers have come to depend on from Preeminence .

Cast iron wear rings - fitted as standard, replaceable front & rear wear rings with optional materials, for a trouble-free lifecycle.
SS304 impeller - in a closed design is fitted as standard to prevent corrosion in stationary or inactive situations. 316SS or Cast iron are available on request. The use of 3-D solid model (CAD) Computer Aided Design and (CFD) Computational Fluid Dynamics ensures high efficiencies, reducing overall running costs. Impeller diameters can be trimmed to suit specified performance. PISO impellers are be balanced, providing smooth, vibration free operation, preventing premature bearing failure.
Pump casing - highly efficient cast iron volute casings, Flange dimensions and drilling according to AS/NZS 4331.2 ISO 7005.2 - 16 bar (EN) and DIN 2533/16 Bar. AS2129, Table E available on request
Casing o-ring - re-usable o-rings in Nitrile for ease of re-assembly (optional materials available).
