A: Yiw, aguadidan dodow no ara ma kwan ma wɔsesa nneɛma a ɛwɔ mu no anammɔn biara. Wubetumi akɔ pɔmpɛ no ti no mu de ahyɛ nhyɛso switch, diaphragm, ne check valves no ananmu denam standard rebuild kits so a enhia sɛ wosesa motor assembly no nyinaa.

Asɛmmisa: Nsonsonoe bɛn na ɛda demand pump ne bypass pump a ɛwɔ sprayers mu ntam?

A: Demand pumps dum koraa bere a trigger no to mu, na ɛde ne ho to pressure switch so sɛ ɛbɛbubu anyinam ahoɔden circuit no. Bypass pɔmpɛ kɔ so yɛ adwuma bere mpo a wɔato trigger no mu no; wɔde nsu a wɔahyɛ no den san kɔ tank no mu de kɔ so kura nhyehyɛe no nhyɛso mu a wɔrensiw motor no kwan.
