1. Isikhombisi-ndlela Sokuzungezisa: Ukuthi ingabe iphampu izungeza ngokwewashi noma ngokuphambene newashi uma ibukwa kusukela ekugcineni kwenjini (ukuhlelwa kwegumbi lokumpompa kuhilelekile lapha).

Kusukela ohlangothini lwe-motor: uma iphampu ijikeleza ngokuphambene newashi, i-pump inlet ingakwesokunxele futhi i-outlet ingakwesokudla; uma iphampu izungeza njengokuya kwewashi, i-pump inlet ingakwesokudla futhi i-outlet ingakwesokunxele.

2. Ifomu lokuvala:iphampu yecala lokuhlukanisaipakisha izigxivizo, izigxivizo ezithambile noma izigxivizo zemishini.

3. Indlela yokugcoba: kungakhathaliseki ukuthi i- icala lokuhlukanisa iphampu iwukugcoba amafutha noma ukugcoba uwoyela omncane. (wonke amaphampu wecala elihlukanisiwe enkampanini yethu amake indlela yokugcoba).
