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
Macro Pump
The larger frame in the magnetic drive gear family, for transfer duty that has outgrown a micro pump but still cannot have a seal.
Overview
What This Pump Does
The macro pump takes the same magnetic drive gear principle to a larger frame. Transfer applications focus on moving enough liquid to a point of use without altering its characteristics, and that is what this build is sized for.
Typical work is batch feed and waste extraction, fluid and water supply systems, and hazardous fluid handling where a sealed pump would be a liability.

Key Benefits
More Flow Without Adding A Seal
Higher Transfer Capacity
A larger gear set moves more liquid per revolution while keeping the seal free construction.
Liquid Is Not Altered
Transfer duty is about delivering liquid unchanged, without shear or aeration.
Hazardous Fluid Handling
No leak path makes it a reasonable choice for fluids that must stay contained.
Speed Controlled Flow
Rate follows shaft speed, so the same pump can serve several transfer rates.
Application Scenarios
Where It Is Installed
Batch Feed And Waste Extraction
Moving a measured batch into or out of a process vessel.
Fluid And Water Supply
Supply systems inside equipment and small plant installations.
Hazardous Fluid Transfer
Handling fluids where containment matters more than pump cost.
Who It Is For
- Process engineers on small transfer duties
- Equipment builders needing more flow than a micro pump gives
- Laboratories moving batches between vessels
- Plants handling fluids that must stay contained
Problems It Solves
The micro pump is too small
A larger gear set gives more flow without moving to a sealed pump design.
Transfer changes the liquid
Gear transfer avoids the shear and aeration a small centrifugal pump introduces.
Containment requirements
No shaft through the housing means nothing to leak during transfer of hazardous fluid.
Technical Features
How It Is Built
- Magnetic drive external gear pump in a larger frame
- Transfer duty focus with unchanged liquid characteristics
- No shaft seal
- Flow proportional to speed
- Suited to batch feed, waste extraction and supply systems
- PEEK gear option for sensitive liquids
Specifications
Technical Data
Send required flow, differential pressure and the liquid. Transfer duty is usually limited by pressure, not by the flow figure alone.

Compared With Other Options
| SKQB micro pump | Same principle, smaller frame. Choose the SKQB for precision low flow and this build for transfer volume. |
|---|---|
| Small centrifugal transfer pump | A centrifugal pump is cheaper at higher flow but needs a seal and alters the liquid through shear and aeration. |
Use Guide
Using The Pump On Transfer Duty
Check Differential Pressure
Transfer over distance or height builds pressure. Size on pressure as well as flow.
Keep The Suction Clean
Fit a filter, since gear pumps are damaged by particles carried from a dirty vessel.
Avoid Dead Head Running
Never run against a closed valve. Fit relief protection or an interlock.
Record Batch Volumes
Calibrate revolutions against delivered volume so a batch can be dosed by counting.
Answers
Macro Pump FAQ
How much more flow than the micro pump?
It is the larger frame in the family. Send your required flow and pressure and we will confirm which build covers it.
Does transfer change the liquid?
Transfer applications focus on moving liquid without altering its characteristics, which is why gear transfer is used instead of a centrifugal pump.
Can it handle hazardous fluids?
Hazardous fluid handling is one of the listed applications, because there is no shaft seal to leak.
Can it run dry?
No. Protect against an empty suction line.
Is it speed controlled?
Yes, flow is proportional to shaft speed.
