Corrosion-Resistant Non-Metallic Close-Coupled Centrifugal Pumps.
Shertech close-coupled non-metallic pumps produce high flow rates under moderate head conditions. Designed for continuous medium pressure circulation and transfer of non-flammable liquids, water circulation, booster service, irrigation, spraying systems, jockey pump service, aggressive liquid applications, and other general purpose pumping compatible with pump component materials where no suction lift is required. Water seal flush port is provided for the decontamination of chemicals on the seal and seat elastomers.
NORYL SERIES (black) – This series is designed for industrial chemical applications. The pumps are made of Noryl, which is non-metallic, chemical-resistant to most acids, alkalis, and inorganic solvents. This material is stiffer under pressure and temperature than the Polypropylene series. The Noryl series handles inlet booster pressures to 30 psi and a maximum temperature of 180° F. These pumps can be equipped with a unique chemical-resistant carbon ceramic mechanical seal with Viton elastomer having the stainless steel components sealed in Noryl allowing for a complete non-metallic Noryl wet end. This unique seal guarantees reliability through simplicity and balance of design. Even the motor and pedestal drive shaft is protected by the seal design.
POLYPROPYLENE SERIES (white) – This series is designed for light industrial or commercial water-based applications. The pumps are made of non-metallic, glass-filled polypropylene construction offering chemical resistance to most acids, alkalis, and inorganic solvents as does the Noryl series. The difference is these pumps are typically equipped with a carbon ceramic mechanical seal with Buna-N elastomers with the stainless steel components that are not sealed, but still protect the motor or pedestal shaft from chemical exposure. The Polypropylene series cannot handle added inlet booster pressures and is rated for a maximum temperature of 140° F. However, upgraded chemical-resistant, polyprop-encased seals are available. |
