Pump size: 109*88.6*43.6mm
Pump weight: 600g;
Outlet: OD 8.5mm, Hose recommendation: ID 10mm
Material: Pump body: PPS, Diaphragm: PTFE
Due to the use of ball bearings, the performance of the pump is stable and high.
The diaphragm is made of PTFE and the pump body is made of special PPS, which makes the pump have good durability and strong chemical resistance.
