Series Overview
Key specifications shared across the Z 0.75-7.5 kW series.
Published data specifies IP68 protection, class F insulation, water temperature up to 40°C, pH 6-10 and three-phase 380 V +/-10% at both frequencies. The S and SF configurations shown in this entry use single-phase 220 V.
Model Range
Compare hydraulic performance across all available power ratings.
Eighteen performance selections, 50 Hz and 60 Hz separated. Each frequency cell shows rated flow / head and maximum flow / head in GPM / ft. Published data marks two 80 mm models unavailable at 60 Hz.

SOURCE & REVIEW
Evidence stays tied to this Z entry.
Published source
MEUDY sewage pump catalog 2026.6.6, printed pages 70-73 with specifications, materials, 50/60 Hz curves, R/Y dimensions and Z auto-coupling dimensions.
Current catalog
Twenty-seven counted frequency records come from current English Z base and S codes; SF float options remain outside the count.
Confirmation
Missing 60 Hz records, empty 50 Hz outlets, the 100Z27.5 head conflict, certification scope and North American suitability require confirmation.
Z SERIES FAQ
Selection questions answered from evidence.
How many models are in the Z 0.75-7.5 kW 2P range?
Published data groups 18 hydraulic selections in one Z product entry. Counted page codes are the base and S forms (18 codes, 27 frequency records). Matching SF float-switch codes 50Z2.75SF and 50Z21.1SF remain outside that count.
What do the S and SF codes mean on this page?
Published data table identifies the S rows as single-phase 220 V and explicitly states that Z...SF is single phase with a float switch. This page does not apply that suffix rule to other pump families.
Does every Z model have a current 60 Hz catalog record?
No. The current catalog has 11 matching 60 Hz records. Nine exact codes have no 60 Hz record, and published data specifically marks 80Z22.2 and 80Z23.0 as unavailable for 60 Hz.
Why do 50 Hz outlet cells show a dash?
All counted 50 Hz catalog records leave outlet diameter empty, while counted 60 Hz records list 50, 65, 80 or 100 mm. Published data outlet values remain visible in the hydraulic table.
Why is the 100Z27.5 maximum head flagged?
Published data lists 135 ft maximum head at 60 Hz, while the current 100Z27.5 60 Hz catalog record states 131 ft. Confirm the quotation value against an approved curve.
