Customer Reviews for VEVOR Air-Operated Double Diaphragm Pump 1 inch Inlet/Outlet 30GPM Polypropylene Max 100PSI for Chemical and Industrial Use

perfect works great for our application

llego antes de lo esperado, super.

BUEN FUNCIONAMIENTO Y CARACTERISTICAS CORRECTAS

Bought this a few months back as a replacement to a more expensive brand. Use it in our waste water treatment which regularly sees both high and low pHs. It has been working with no issues. Only difference I see with this and our previous pump is that there is a higher threshold in air pressure to get the pump going. Setting a lower flow rate that switches on and off automatically, as in our case, can be a challenge.

La pregunta es, son correctas las unidades? Es muy poco caudal 2.5 gpm para una bomba con conexiones de 1/2". Las bombas comerciales de 1/4" ofrecen hasta 4.5 gpm!!! Incluso la placa de datos de la bomba vevor también menciona 2.5 gpm Si la requieres para reventa, el cliente no la compra, porque duda por este dato Será que las unidades deben de ser en m3/hr?
