Series Overview
Key specifications shared across the KBV series.
Published data describes a small outside diameter for narrow spaces, a motor side-wall discharge channel for cooling, and a large clearance around the semi-open impeller to reduce sticking from mud or sand. The hose coupling can be vertical or oblique.
Model Range
Compare hydraulic performance across all available power ratings.
Printed pages 29-31 define KBV separately from KBVE. the published footnote identifies KBV as three phase and KBVM as single phase; maximum head is printed as separate 50/60 Hz values.

Current 60 Hz records are not listed for KBVM21.5, KBVM31.5 or KBV31.5. Current decimal endpoints also differ from rounded published values, including KBV45.5 at 245.2 GPM for 50 Hz versus 237.8 GPM in published data. Confirm the approved curve before quotation.
Construction & materials
Light-alloy motor structure with a rubber wet end.
Published data narrative calls the impeller high-chrome cast iron, while its component table lists ductile iron with high-chrome alloy as an option. This internal source difference requires confirmation before quotation.

SOURCE & REVIEW
Evidence stays tied to KBV.
Published source
English engineering-pump published printed pages 29-31 with description, specifications, materials, dimensions, 50/60 Hz curves and 11 performance rows.
Current catalog
Nineteen matching frequency records, seven content-distinct product images and 11 dimension paths representing seven content-distinct drawings.
Confirmation
Missing 60 Hz records, impeller-material wording, certification scope, North American electrical suitability and final duty selection require confirmation.
KBV FAQ
Model grouping, hydraulics and construction.
How many published models belong on the KBV page?
The published data has 11 models under the KBV Contents item: nine three-phase KBV models and two single-phase KBVM models.
Are KBVE and KBVME included on this page?
No. KBVE is the next independent Contents item in published data. Its intelligent KBVE and KBVME catalog records are not merged into this KBV page.
Which published frequencies are missing from the current catalog?
Published data covers 50 Hz and 60 Hz, but current 60 Hz records are not listed for KBVM21.5, KBVM31.5 or KBV31.5.
Can the KBV hose coupling be repositioned?
Published data states that the hose coupling can be installed vertically or obliquely to reduce folding or bending of a soft hose.
Which impeller material does published data specify?
The narrative calls the impeller high-chrome cast iron, while the component table lists ductile iron with high-chrome alloy as an option. Confirm the supplied impeller before quotation.
