Varisco
Product Overview
Features and benefits
- Available in several material options.
- An open impeller can handle suspended particles up to 76 mm in size.
- Replaceable rubber-coated wear plates help ensure a long service life.
- The design makes it possible to replace submersible pumps with dry-mounted, service-friendly installations. Suitable for sewage pumping stations where the pump is placed in an above-ground pump housing for easier maintenance.
- The design, which includes a built-in check valve, provides a suction head of up to 7.5 m.
- Front-mounted inspection hatches and a back-pull-out design facilitate easy maintenance and inspections.
- The pumps are available in many different material combinations and designs to optimally suit each application.
- Conical seal chamber with internally mounted balanced Tungsten Carbide seals as standard provides long service life.
Specifications
- Capacity: flow rates up to 420 m³/h and head up to 35 m.
- Temperature ranges -10 °C ÷ + 80 °C (higher on request)
- Materials: Parts in contact with liquids are available in several material combinations, such as cast iron and acid-resistant AISI 316 stainless steel. Special materials are available upon request.
- Elastomer: NBR, VITON®, and PTFE
- A range of options such as. ATEX design, cutting impellers, mobile arrangements, provide a wide range of applications.

The cantilever design eliminates guide bushings near the impeller, removing a common area of wear and ensuring safe and trouble-free operation even in demanding process environments.
CGI-L/CDI-QL series (LIBRA) - Chemical norm centrifugal pump ISO 2858/5199
The CGI-T is a horizontal centrifugal pump series, designed in accordance with ISO 2858 / EN 22858 standards and developed to cope with demanding industrial applications. The pumps are very robust, with heavily oversized components that ensure maximum reliability and long service life.
TCT series - Chemical norm centrifugal pumps with vortex impellers ISO 2858
The TCT series is a centrifugal pump with an open vortex impeller, designed for handling liquids containing suspended solids or fibers, as well as slurry and viscous media.
The pump is based on the TCH series design and uses several common components, which simplifies maintenance and reduces the need for spare parts. The vortex principle ensures that the liquid is handled by the swirling motion of the impeller, providing gentle handling of contaminated and particulate-laden media.
MSP-N/MSP-L series - Magnetic drive self-priming centrifugal pump
The MSP-N and MSP-L series is a magnetic drive self-priming centrifugal pump for applications with high demands on safe and leak-free operation. They offer powerful and stable performance while protecting both process and environment.
The pumps are designed for installations where it is not possible to install standard conventional centrifugal pumps when the need for self-priming function is desired.
