Micro Gear And Magnetic Drive Pumps
SKQB Micro Pump
Magnetic drive micro gear pump for precise low flow duty.
View specifications →Micro Gear And Magnetic Drive Pumps
Magnetic Gear Pump
The circulation build of the magnetic drive family, for loops that have to keep running for months without anyone touching them.
Overview
What This Pump Does
The magnetic gear pump moves liquid through a closed circuit with an external gear set driven magnetically. Circulation duty puts the emphasis on reliable operation over extended periods rather than on peak flow.
Typical circuits are heating, cooling, filtering, mixing, hydrating, degassing, venturi feed and system pressure control, where the pump runs continuously and access for service is limited.

Key Benefits
Built For Duty That Never Stops
Designed For Long Runs
Circulation applications emphasise reliable operation over extended periods, which is how this build is specified.
Nothing To Leak
No shaft seal means no gland to weep into the equipment it is installed in.
Stable Flow
Gear displacement keeps the circulation rate steady as system conditions change.
Compact Installation
A small head and standard motor frame fit inside machines and cabinets.
Application Scenarios
Where It Is Installed
Temperature Control Loops
Heating and cooling circuits inside equipment where flow must stay constant.
Filtration Circuits
Circulating liquid through a filter at a steady rate rather than in bursts.
Degassing And Conditioning
Hydrating, degassing, venturi feed and system pressure control duties.
Who It Is For
- Equipment builders with internal liquid circuits
- Laboratories running conditioning loops
- Process engineers on small closed circuits
- Maintenance teams replacing leaking circulation pumps
Problems It Solves
A leaking pump inside a machine
Liquid escaping from a gland inside an enclosure damages far more than the pump. A sealed housing removes that risk.
Circulation rate drifts
Positive displacement keeps the rate tied to speed, not to filter loading or system pressure.
Service access is poor
Fewer wear items means fewer interventions in places that are hard to reach.
Technical Features

Specifications
Technical Data
Circulation duty is defined by flow and circuit resistance. Send both, along with the liquid and its temperature.

Compared With Other Options
| SKQB micro pump | Same family. This build is specified around continuous circulation rather than metering accuracy. |
|---|---|
| Centrifugal circulator | A small centrifugal circulator is cheaper but its flow changes with system resistance and it needs a seal. |
Use Guide
Keeping A Circulation Loop Reliable
Filter The Circuit
Install and maintain a filter. Debris is the main cause of wear in a circulating gear pump.
Vent At Commissioning
Remove air from the loop so the pump is not asked to run on gas.
Check Flow Periodically
A slow drop in circulation usually means wear or a blocked filter, not a failed motor.
Plan A Spare
On a critical loop hold a spare head, since replacement is quicker than repair.
Answers
Magnetic Gear Pump FAQ
What circuits is it used in?
Heating, cooling, filtering, mixing, hydrating, degassing, venturi feed and system pressure control.
How long can it run continuously?
Circulation builds are intended for extended periods of operation with clean liquid and a filtered circuit.
Does flow change as a filter blocks?
Very little, because displacement per revolution is fixed. Pressure rises instead, so monitor pressure to spot a blocking filter.
Can it be speed controlled?
Yes. Flow is proportional to speed, so a variable speed drive gives direct control.
Is there a seal to replace?
No dynamic seal at all. The drive is magnetic through a closed housing.
