Air-Operated Double Diaphragm Pump
An air-operated double diaphragm pump uses compressed air to reciprocate two flexible diaphragms, creating a positive displacement action that transfers viscous liquids and slurries. Despite being pneumatically driven, the pump's liquid displacement mechanism is reciprocating, qualifying it under this tariff item for other reciprocating positive displacement pumps.
Bilge Reciprocating Pump
A bilge reciprocating pump is a compact piston pump designed to remove water from boat bilges. Its reciprocating piston action provides positive displacement, making it suitable for this tariff item. The self-priming feature is typical for marine applications where the pump must operate above the water level.
Brewery Transfer Piston Pump
A brewery transfer piston pump uses a reciprocating piston to gently move wort, beer, and syrup without damaging shear-sensitive liquids. Its hygienic design meets food safety standards, and the positive displacement action ensures consistent flow. This pump is classified under this tariff item as a reciprocating positive displacement pump for liquids.
Chemical Reciprocating Plunger Pump
A chemical reciprocating plunger pump is built with corrosion-resistant materials like PTFE seals to handle aggressive chemicals. Its reciprocating plunger creates positive displacement, enabling high-pressure transfer up to 100 bar. This pump is classified under this tariff item as a reciprocating positive displacement pump for liquid chemicals.
Diaphragm Metering Pump
A diaphragm metering pump uses a flexible diaphragm that reciprocates to displace precise volumes of chemicals for dosing. The positive displacement action is driven by a reciprocating mechanism, making it eligible for this tariff item. It is commonly used in water treatment and chemical injection applications.
Dosing Pump for Water Treatment
A dosing pump for water treatment is an electrically driven reciprocating piston pump that accurately doses chemicals into water purification systems. Its positive displacement mechanism ensures precise chemical delivery, qualifying it under this tariff item. The adjustable stroke allows for variable flow control in treatment processes.
