What the K2000 Does
The K2000 is a compact pneumatic grease pump built around a 4 L reservoir. It moves grease at a working pressure of 2-3 MPa (290-435 psi) using compressed air from 0.4-0.6 MPa. The pump is intended for workstations, bench tasks, and light centralized supply where an electric motor is unwanted.
Each stroke delivers an adjustable 2-10 ml of grease. The pump can run at up to 30 cycles per minute, giving a theoretical maximum of 300 ml/min at full stroke and full rate. Sustained flow depends on air supply and grease stiffness. The outlet thread is M10x1, and the unit accepts grease from NLGI 00 to 2.
The K2000 weighs 4-6 kg and mounts on a wall or shelf. It is the small, portable member of the pneumatic family, sized for a bench slot rather than a drum top. The pump has no electrical ignition source, so it can be placed where shop air is already available and electrical supply is not desired.

How Air Drive Works
Compressed air enters through a 1/4 in. NPT or G1/4 inlet and acts on the pump mechanism. The pump has no electrical ignition source, which removes the need for an electric motor at the point of use. Air consumption runs 150-250 L/min at 0.5 MPa, so the supply line must be sized for that draw.
Stroke volume is set between 2 and 10 ml, and cycle rate is set up to 30 cycles per minute. The two settings are independent, so a small stroke at a high rate and a large stroke at a low rate both remain possible. The pump stops when air supply stops, and it resumes when air returns.
An FRL unit upstream is recommended. The FRL removes water and regulates air pressure before it reaches the pump. Dry, regulated air keeps the drive consistent and protects the internal air path.
Where It Fits in the Pneumatic Family
The K2000 is the bench-slot sibling in the pneumatic range. It sits below the 25 kg drum pump in reservoir size and above a hand-loaded pneumatic grease dispenser in output control. It is not a drum-top unit, and it is not a handheld dispenser.
For higher working pressure, the high-pressure grease pump page covers a different output band. For lower pressure tasks, the low-pressure grease pump page shows the other end of the range. The pneumatic selection hub places all of these side by side for comparison.
When the K2000 feeds more than one point, it can work with small progressive or single-line setups. The layout must be confirmed when ordering, because the pump alone does not divide flow. The central lubrication overview explains how a pump, metering devices, and lines work together.
Air Supply and FRL
The K2000 expects shop air between 0.4 and 0.6 MPa. Below that band, stroke force drops and delivery becomes inconsistent. Above it, the drive can cycle faster than intended and wear increases.
An FRL unit upstream is recommended, not optional in practice. The filter removes water and particles, the regulator holds pressure steady, and the lubricator conditions the air motor. Without an FRL, wet or dirty air shortens seal life and makes stroke timing erratic.
Air consumption is 150-250 L/min at 0.5 MPa. A small compressor that cycles often may not hold that draw during continuous operation. For intermittent bench use, a modest shop air line is usually enough. For help sizing the air supply, use the quotation contact page.
Stroke, Rate and Grease Grades
Stroke volume adjusts from 2 to 10 ml per stroke. Cycle rate adjusts up to 30 cycles per minute. The product of the two gives a theoretical maximum of 300 ml/min at full stroke and full rate. Sustained flow depends on air supply and grease stiffness.
The grease window is NLGI 00 to 2. Higher NLGI numbers mean stiffer grease: 000 is softest, 3 is hardest. The K2000 accepts 00, 0, 1, and 2, but a stiff grade 2 will move slower than a soft grade 00 at the same air setting.
Ambient range is -10 to +60 °C. Below -10 °C, grease stiffens and pickup from the reservoir becomes unreliable. Above +60 °C, seal material choice matters: NBR or FKM must be specified when ordering.
The 4 L reservoir suits short runs and bench work. Refill frequency is higher than a drum pump, but the small size keeps the unit easy to move and mount. Wall or shelf mounting keeps the pump above the work area and shortens the outlet line.
Frequently Asked Questions
Why choose air drive instead of electric for this size class?
The pump has no electrical ignition source, which removes the need for an electric motor at the point of use. Shop air is usually already available in the same workstations where the K2000 would sit.
What does the FRL unit do for this pump?
The FRL filters water and particles, regulates air pressure, and lubricates the air drive. Dry regulated air keeps stroke timing consistent and protects the internal air path.
How is flow adjusted on the K2000?
Stroke volume is set between 2 and 10 ml per stroke, and cycle rate is set up to 30 cycles per minute. The two settings are independent, so output can be tuned for the task.
What does the NLGI 00 to 2 window mean?
Higher NLGI numbers mean stiffer grease, with 000 softest and 3 hardest. The K2000 accepts 00, 0, 1, and 2, but stiffer grades move slower at the same air setting.
Can the K2000 supply more than one lubrication point?
It can feed small progressive or single-line setups when metering devices are added downstream. The layout must be confirmed when ordering because the pump alone does not divide flow.
How is the K2000 mounted?
The pump mounts on a wall or shelf and weighs 4-6 kg. Mounting above the work area shortens the outlet line and keeps the reservoir easy to refill.
What is the difference between theoretical and sustained flow?
The theoretical maximum is 300 ml/min at full stroke and full rate. Sustained flow depends on air supply and grease stiffness, so real output is usually lower.
What are the trade-offs of the 4 L reservoir?
The small reservoir keeps the unit light and portable for bench work. Refill frequency is higher than a drum pump, which matters on long continuous runs.
How does the K2000 behave in cold conditions?
The ambient lower bound is -10 °C. Below that, grease stiffens and pickup from the reservoir becomes unreliable.
