Self-priming mag drive and mechanical seal pump MNK-S, MNK-SB, SCK-S

Product catalog summary

Overview: The document provides detailed technical specifications and features of Richter self-priming chemical centrifugal pumps, specifically the MNK-S, MNK-SB, and SCK-S models. These pumps are designed for handling corrosive and hazardous liquids, offering a wide range of applications due to their self-priming capabilities and robust construction.

Specifications:

Materials: The pump housing is made of ductile cast iron with a thick PFA/PTFE lining, ensuring corrosion resistance.
Design: Features include a magnetic drive or mechanical seal, with options for frame-mounted or close-coupled configurations.
Performance: Capable of priming against 18 m (59 ft) WC back pressure, with suction lifts up to 6 m (20 ft) WC and delivery capacities ranging from 1-33 m3/h (4-145 US gpm).
Temperature and Pressure: Operating temperature ranges from -60 to +150 °C (-75 to +300 °F), with pressures up to 10 bar (145 psi).

Design Features:

Back Pull-Out Unit: Utilizes a magnetic drive with eddy-current-free can system and SAFEGLIDE® PLUS silicon carbide plain bearings.
Sturdy Construction: Includes a bearing pedestal made of ductile cast iron and impeller with a stable metallic core.
Optimized Flow: The separation chamber is designed for a short priming phase and high efficiency.

Applications: These pumps are suitable for emptying tanks, tankers, and sumps, and are effective in chemical production and waste water management. They can handle liquids with varying compositions and solids-containing media, though consultation with Richter is recommended for the latter.

Additional Features:

Magnetic Drive Pumps: Offer optional SAFEGLIDE® PLUS dry-run optimized bearings and non-metallic, eddy-current-free cans.
Mechanical Seal Pumps: Designed for high loads with options for internal or external double mechanical seals.
Closed Impellers: Feature large metallic cores and optimized-flow curved channels.

Conclusion: Richter's self-priming pumps provide a versatile and efficient solution for handling a variety of chemical and hazardous liquids, with robust design features that enhance performance and reliability.
