Positive Displacement pumps mechanically displace a known volume of
liquid so that the pumps, running at a constant speed, positively displace
a liquid volume at a fixed rate. PD pumps can be subdivided into two main
categories; reciprocating pumps and rotary pumps. SPX Process Equipment offers Air Operated Double
Diaphragm (AODD) pumps as reciprocating pump type and Flexible Impeller, Internal
Gear and Rotary Lobe pumps as rotary pump types.
SPX Process Equipment supplies you with a full range
of Johnson Pump brand documentation depending on need and
local regulations:
• ATEX
• 3A
• EHEDG
• FDA, USP VI
• Material traceability &
certification 2.1, 2.2 and 3.1
• QHP tests
• Vibration tests
• Noise level tests |

Internal Gear Pumps can be used in all
types of manufacturing applications for
the transportation of both thin and thick
materials, from chocolate to diesel fuel.
Rotary Lobe Pumps are easy to
clean and have gentle product-handling
characteristics. They contain few cavities,
which reduces the risk of bacterial growth
and makes them particularly suitable for the
tranport of sensitive fluids – from glue to
whole strawberries.
Air Operated Double Diaphragm
Pumps are used in all types of industries
for transporting a wide variety of liquids.
Clean or polluted, thin or viscous, abrasive
or aggressive.
Impeller Pumps have good suction
characteristics and the ability to pump solid
particles. Impeller pumps have a wide range
of applications in all types of industries. |
