Diaphragm Pumps
Polypropylene and PVDF bodied, light and reliable solution in chemical transfer with a wide model range from 1/4'' to 3''.
About PP Series
Plastic diaphragm pumps (PP Series) are manufactured with polypropylene (PP) or PVDF bodies, exhibiting resistance beyond metal body alternatives against corrosive chemicals such as acids, bases, and solvents. Six main sizes, ranging from the compact PP 02 model with 1/4'' connection to the high-flow PP 30 model with 3'' diameter, cover a very wide range of processes under a single series. The series also includes vertical/side-connection Y variants (PP 02Y, PP 05Y, PP 10Y); these models are preferred in confined installation areas and at piping points where space savings are desired.
The total weight of PP Series pumps is significantly lower compared to metal pumps with equivalent flow capacity; the largest model, PP 30, has a carrying weight of only 49 kg. This lightness facilitates field installation while also reducing transportation and repositioning costs. Structural resistance to dry running provides safe background protection in processes where level fluctuations are intense. The air-operated AODD architecture offers a natural advantage in fields without electrical infrastructure or those within EX zones.
The PVDF body option further extends the pump's temperature resistance and chemical compatibility; PVDF is preferred for processes that exceed the limits of the PP body, particularly against oxidizing acids (HNO₃, HClO₄), organic solvents, and various fluorine compounds. In applications for use in the food industry, the combination of FDA-approved PVDF body and PTFE diaphragm guarantees product purity and absence of trace contaminants. On the elastomer side, fluid-specific selection can be made from Santoprene, Neoprene, Buna-N (NBR), EPDM, FKM, and PTFE; this flexibility makes the PP Series one of the most customizable diaphragm pump families.
Technical Specifications
The polypropylene housing demonstrates high chemical resistance against dilute acids, bases, salt solutions and non-polar solvents. With the PVDF option, this resistance extends to oxidizing acids and organic halogenated compounds.
The PP 30 model is one of the lightest AODD options in large size with only 49 kg. The lightweight body allows for temporary or mobile installation instead of permanent ground mounting; it can be positioned by field crews without requiring a crane.
The PP Series does not cause permanent damage to the body or diaphragm when it continues to operate without fluid. Additional protective systems are not required in level fluctuation and pump priming entry scenarios.
The PP Series, with its pneumatic operating principle without electricity and conductor/antistatic material options, can be safely deployed in Zone 1–2 (gas) and Zone 21–22 (dust) explosive atmospheres.
The PP Series with Santoprene, Neoprene, Buna-N, EPDM, FKM and PTFE diaphragm options allows full customization according to temperature, chemical compatibility and cost parameters.
PP 02Y, PP 05Y and PP 10Y models eliminate plumbing restrictions with vertical and side connection points. While delivering the same hydraulic performance as standard models, they adapt to different assembly geometries.
