The hand pump can be fixed using one of the supplied rubber adapters in the bunghole of a barrel or canister.
By actuating the pump lever, pressure is built up in the container. The pump can be easy and safe operated with one hand.
The user has two different operating options:
If small quantities should be exactly removed with the hand pump, only the tap must be pressed. This enables to fill small containers or even flasks and test tubes easily and safely by lever pressure.
Alternatively, these hand pump works as a siphon pump with a flow rate of 20 l/min, if the tap is completely folded forward before pumping.
The advantages are evident:
Precise dosing possible.
No permanent pumping necessary. The user has both hands free. This increases the safety when pumping slightly aggressive or alkaline media.
The pump is available with three different seals (NBR, EPDM or FKM).
Each hand pump is supplied with three rubber adapters (depending on the pump made of NBR, EPDM or FKM), suitable for bunghole diameters from 46.5 to 60 mm, thus ensures a flexible adaptation to all common bunghole openings. For the assembly of the pump no special tools are required.
The pumps are operated manually. Therefore they can be used in areas without electricity or compressed air connection.
In the future, a version with a Hastelloy spring in tap is planned, so that aggressive chemicals such as hydrochloric acid can be pumped. In addition, a series of PVDF to be produced to dispense highly corrosive substances such as chromic acid, hydrofluoric acid and nitric acid easy and safe.
