To expertly balance axial thrust, our pumps boast wear rings at both the front and rear of most impellers, complemented by a balance hole on the impeller's back shroud. In instances where the axial thrust is minimal, these components may not be necessary, optimizing the pump's efficiency without them.
Crafted with high-precision casting techniques, our impellers deliver exceptional performance. Available in robust materials such as cast iron, stainless steel, and bronze, they ensure durability and reliability under various operating conditions.
The pump cover, designed for enhanced functionality, is fitted with stuffing for soft packing seals. This innovative feature allows for the passage of pressurized water to cool, lubricate, and clean the seal, ensuring optimal operation and longevity.
Our pumps offer versatile sealing options with both single and double mechanical seals. Designed to ISO3069 standards, they incorporate a pressurized water system to cool and clean the seal's friction surface, while options like corrugated pipe and expeller seals provide adaptable solutions for specific needs.
Flexible Couplings
Flexible couplings, a step above rigid counterparts, offer exceptional resilience by accommodating movement such as vibrations and thermal expansion without sustaining damage. Ideal for applications with slight misalignments between drive and pump shafts, they reduce excessive noise and protect components from premature wear, resulting in long-term maintenance savings despite their intricate design.
Our pump systems utilize wear-resistant disc couplings or pin couplings, chosen for their durability and reliability in demanding environments.
