KNOLL PUMPS
KNOLL manufactures screw-spindle and centrifugal pumps for industrial coolant management, machine tools, and process-fluid transfer. Its product families include high-pressure coolant pumps, self-priming block pumps, clean- and contaminated-coolant pumps, and shredder pumps for aluminum chip handling.
Great Lakes Pump & Supply provides KNOLL pumping equipment for metalworking, machining coolant circulation, filtration systems, and compatible industrial process applications. The correct pump depends on whether the liquid is filtered coolant, coolant containing chips or entrained air, or a process fluid requiring specialized viscosity and pressure handling.
KNOLL Pump Products for Coolant, Process, and Industrial Fluid Applications
KNOLL pumps perform different functions within industrial fluid-handling systems. KTS and KTSL screw-spindle pumps deliver cleaned coolant at elevated pressures for machine tools, while KTSV screw pumps are designed for transferring or dosing process media across a broad viscosity range.
KNOLL centrifugal pumps include BS self-priming block pumps for coolant containing air, TG pumps for cleaned coolant with residual contamination, and TF, TS, TSK, and TSL pumps for more heavily contaminated coolant and chip mixtures.
For applications involving long aluminum chips, KNOLL TSC shredder pumps combine chip reduction and coolant transport within the pumping process.
These distinctions are particularly important in centralized coolant systems, where pumps may serve different functions before and after filtration. Selecting a pump solely by flow rate or connection size can overlook solids content, required discharge pressure, coolant condition, and installation requirements.

Screw Pumps
KTS Screw Pumps
KNOLL KTS three-spindle screw pumps are designed to deliver cleaned cooling lubricants at high pressure to machine tools. Typical uses include supplying coolant through internally cooled cutting tools during drilling, milling, and related machining operations.
Common applications: High-pressure coolant supply, through-tool cooling, machining lubrication, and chip evacuation at the cutting tool.
KTSL Screw Pumps
KNOLL KTSL screw pumps provide a compact configuration for high-pressure coolant delivery in standard metalworking applications. Available installation arrangements include vertical immersion and suitable dry-mounted configurations.
Common applications: Machine-tool coolant supply, internal tool cooling, drilling, milling, and industrial metalworking.
KTSV Screw Pumps
KNOLL KTSV screw pumps are designed for conveying and dosing process media ranging from low to very high viscosity. Depending on the configuration, they can accommodate shear-sensitive or abrasive materials and specialized process requirements.
Unlike the KTS and KTSL coolant-delivery pumps, the KTSV is intended for a broader range of process-fluid applications.
Common applications: Process-fluid transfer, viscous liquid handling, controlled dosing, and compatible industrial chemical or material-processing systems.
Block Pumps
BS 32, BS 40, and BS 50 Block Pumps
KNOLL BS Series self-priming centrifugal pumps are designed to transport coolant containing entrained air and suitable contamination. They can support coolant-return arrangements where air in the liquid creates challenges for conventional pumping configurations.
The BS 32, BS 40, and BS 50 provide different hydraulic capacities and connection arrangements.
Common applications: Machine-tool coolant return, contaminated coolant transfer, and suitable coolant-handling installations with elevated air content.
Clean Coolant Pumps
TG Clean Coolant Pumps
KNOLL TG centrifugal pumps are intended to move cleaned cooling lubricants that may still contain limited residual contamination. These pumps can supply filtered coolant from tanks or filtration systems back to machine tools.
Common applications: Filtered coolant circulation, coolant supply to machining equipment, and industrial coolant distribution.
Selection consideration: Confirm the allowable residual contamination and required flow and head for the selected TG model. A clean-coolant pump should not be substituted for a dirty-coolant pump without reviewing the liquid conditions.
Dirt Coolant Pumps
TF, TS, TSK, and TSL Dirt Coolant Pumps
KNOLL dirty-coolant centrifugal pumps are designed for transporting cooling lubricants containing chips and other compatible contamination. They help move the coolant-and-chip mixture from machining operations to filters, separators, or central processing systems.
The TF, TS, TSK, and TSL families provide different hydraulic arrangements for varying contamination and pumping conditions.
Common applications: Machining coolant return, chip-and-coolant transfer, central filtration systems, and contaminated-coolant circulation.
Selection consideration: Chip type, size, concentration, entrained air, immersion depth, and hydraulic requirements affect which pump family is appropriate.
Shredder Pumps
TSC 50 and TSC 65 Shredder Pumps
KNOLL TSC shredder pumps combine centrifugal pumping with an integrated cutting mechanism designed to reduce long aluminum chips into sizes suitable for transport with coolant.
These pumps can move the resulting coolant-and-chip mixture toward central processing equipment, potentially reducing the need for a separate chip-reduction stage in compatible installations.
Common applications: Aluminum machining, aluminum chip reduction, contaminated-coolant transfer, and centralized coolant processing.
Selection consideration: The manufacturer's stated shredding application is aluminum chips. Other chip materials and sizes require separate suitability verification.
Selecting a KNOLL Pump for Your Application
Selecting a KNOLL pump begins with identifying the pump's function within the fluid-handling system. High-pressure coolant delivery, filtered-coolant circulation, contaminated-coolant return, viscous process-fluid transfer, and chip shredding require different equipment.
For machine tools requiring high-pressure coolant through cutting tools, KTS and KTSL screw pumps are designed for cleaned coolant service. Pump selection should consider the required operating pressure, coolant flow, filtration quality, motor requirements, and installation arrangement.
KTSV screw pumps address a different requirement: transferring or dosing process media with varying viscosity and other challenging fluid characteristics. Viscosity, temperature, abrasiveness, material compatibility, shear sensitivity, and discharge pressure should be evaluated against the selected pump configuration.
For coolant circulation, the difference between clean and contaminated coolant is critical. TG pumps handle cleaned coolant with limited residual contamination. TF, TS, TSK, and TSL pumps are intended for coolant containing chips and other suitable contamination, while BS block pumps are particularly relevant where entrained air affects coolant transfer.
TSC shredder pumps should be considered when long aluminum chips must be reduced before or during transport to the filtration system. Their suitability depends on the chip characteristics, coolant flow, and downstream handling equipment.
When replacing existing equipment, the KNOLL model number, pump curve, motor specifications, installation depth, suction and discharge connections, coolant characteristics, chip size, and required operating conditions can help identify an appropriate replacement.
