What is Pumps for chemicals?
The “Pumps for chemicals” category is a collection of industrial-grade chemical transfer and handling equipment designed for safely moving corrosive, viscous, or hazardous liquids. It includes manual piston pumps, pneumatic double diaphragm pumps, and electric transfer pumps—used by engineers, safety managers, and procurement professionals seeking rated fluid pumps for acids, bases, strong chemicals, viscous liquids, and industrial transfer applications.
Products You’ll Find in This Category
This category features manual piston pumps engineered for strong chemicals and acids, ideal for drum dispensing with materials like Teflon seals and polypropylene components. Pneumatic double diaphragm pumps are available in several flow capacities—such as 55 L/min, 100 L/min, and 165 L/min—these are self-priming, dry-running capable, and constructed with materials including aluminium housings, Hytrel®/PTFE diaphragms, and Viton® seals. Also included are electric transfer pumps for chemicals with suction pipes made from polypropylene, stainless steel (AISI 316), or PVDF. These electric models are designed for use in drums or IBC tanks and include suitable safety features.
Applications & Industry Use Cases
Pumps for chemicals are applied in chemical processing plants for transferring acids, bases, or aggressive solvents between containers. In laboratory and pharmaceutical environments, manual piston pumps are used for precise dosing of strong chemicals, nitric acid or other reagents. Pneumatic double diaphragm pumps are commonly deployed in industrial washing, abrasive mixing, or where fluids contain particulates, due to their dry-running capability and robust construction. Electric transfer pumps serve fluid transfer from drums or IBCs in manufacturing, water treatment, or agrochemical sectors, where viscosity or compatibility of wetted materials—like PVDF or stainless steel—is critical.
Technical Guide to Pumps for chemicals
Pumps for chemicals are designed to transport or lift liquids that may be corrosive, viscous, or laden with particulates. Key parameters include flow rate (e.g., 55 L/min, 100 L/min, 165 L/min for double diaphragm types), maximum suction lift (often around 5 m), and viscosity handling up to certain thresholds (~900 cps for some electric transfer models). Wetted materials—such as PTFE, Viton®, Hytrel®, stainless steel (AISI 316), polypropylene, or PVDF—are selected based on chemical compatibility.
Pneumatic double diaphragm pumps are air-powered, self-priming, and capable of dry running, useful when electricity is not available or fluids are flammable. Electric transfer pumps use impellers driven by motors (230 VAC or 12/24 VDC versions), often with safety switches to prevent accidental activation after power loss. The manual piston pump is operated by hand, suitable for drums 60–220 litres, using chemical-resistant seals and polypropylene components.
Standards and certifications play roles: e.g., ATEX 2014/34/EU compliance for pneumatic diaphragm pumps intended for use in explosive atmospheres; CE marking for electric pumps. Selection considerations include fluid viscosity, solids content, chemical aggressiveness, temperature limits, safety classification of environment (hazardous area or not), required flow rate, suction lift, and power supply availability. Material compatibility, pump type (manual, pneumatic, electric), and background environment (indoor lab vs plant floor) all impact performance.

Frequently Asked Questions about Pumps for chemicals
- What liquid viscosities can these pumps handle?
- The electric transfer pumps in this category support viscosities up to around 900 cps. Pneumatic diaphragm pumps also handle higher viscosities and occasional solids, subject to the model’s rated capacity.
- Which wetted materials are available, and how do I choose among them?
- Wetted materials include PTFE, PVDF, polypropylene, stainless steel (AISI 316), and elastomers such as Viton®. Selection depends on the chemical’s corrosiveness, temperature, and any solids; PVDF and PTFE are suited to aggressive chemicals, stainless steel for neutral or less aggressive fluids, while Viton® seals provide resistance to many chemical agents.
- What is suction lift and why does it matter?
- Suction lift refers to the vertical distance between the pump inlet and the fluid source; several pneumatic diaphragm pumps listed can self-prime to about 5 m. This parameter affects installation and pump selection when fluid sources are below pump level.
- Are any products compliant with hazardous-area or explosive-atmosphere standards?
- Yes. Pneumatic double diaphragm pumps in this category are constructed in accordance with ATEX 2014/34/EU – zone 2, suitable for certain hazardous environments.
- What safety features come with electric transfer pumps?
- Electric models offer features such as safety switches to prevent unintended activation after power loss, immersed suction pipe requirement, and temperature range limits, ensuring safe operation during chemical transfer from drums or IBCs.
