What the PPS-30 Pump Is
The PPS-30 is a small air-operated single-stroke piston pump for a single-line lubrication system. It is a compact pneumatically operated lubricant supply unit, not a barrel-mounted ratio pump. It delivers one stroke per air signal and fits within a small machine envelope without extra brackets.
Official Specifications
The official specification includes these fixed values:
- Output: 30 cm3 per stroke
- Maximum outlets: 3
- Maximum operating pressure: 27 bar
- Reservoir: 1.5 L SAN plastic
- Dimensions: 187 x 246 x 129 mm
- Operating temperature: +10 to +50 C
- Operating viscosity: 20 to 1500 mm2/s
- Lubricants: mineral and synthetic oil, fluid grease NLGI 000 and NLGI 00 only
These values support a compact central lubrication system for small machine zones.
What the Number 30 Means
The 30 in PPS-30 denotes nominal delivery per actuation, not a pressure multiplication factor. A common error is reading the number as an air-to-oil pressure ratio. The pump outputs 30 cm3 per stroke at up to 27 bar system pressure.
Oil and Fluid Grease Limits
This pump accepts mineral and synthetic oil, plus fluid grease NLGI 000 and NLGI 00 only. Ordinary thicker greases are not within the specification. Keep operating viscosity between 20 and 1500 mm2/s.
Pneumatic Piston Versus Electric Gear
The PPS-30 is pneumatic, single-stroke, supports few outlets, and operates at low pressure. An electric multi-circuit gear pump offers electric drive, more circuits, and different pressure behavior. Choose the PPS-30 when compressed air is available and outlet count is small.
Installation and Level Monitoring
Install the pump vertically only, with the 1.5 L SAN plastic reservoir kept upright at all times. Level monitoring is an optional electrical level switch depending on the exact version ordered. For a specific version with level switch, contact the quotation team.
Frequently Asked Questions
What does PPS-30 mean?
The 30 indicates nominal delivery of 30 cm3 per stroke. It does not mean a 30:1 air-to-oil pressure ratio.
How many outlets can this pump feed?
The pump supports a maximum of 3 outlets. It is built for small lubrication circuits, not large multi-point systems.
What is the maximum operating pressure?
The maximum operating pressure is 27 bar. This low pressure suits small single-line lubrication tasks.
Which lubricants are acceptable?
Mineral and synthetic oil are acceptable, plus fluid grease NLGI 000 and NLGI 00. Higher NLGI grades such as standard grease are not within specification.
Can I use a thicker grease than NLGI 00?
No, the pump accepts only fluid grease NLGI 000 and NLGI 00. Thicker greases do not flow within this unit’s viscosity range.
What reservoir size does this unit have?
The reservoir is a 1.5 L SAN plastic tank. The capacity limits the unit to short small lubrication runs.
What is the operating temperature range?
The operating temperature range is +10 to +50 C. The unit must stay vertical during operation.
Is level monitoring included on every version?
Level monitoring is an optional electrical level switch depending on version. Not every unit includes this switch.
How does this pump compare to an electric gear pump?
This pump is pneumatic, single-stroke, and supports few outlets at low pressure. An electric multi-circuit gear pump suits larger systems with more circuits.
Who builds and supports this pump?
