The SB rotary spray head series addresses a specific engineering problem in pumps-what-is-cleaning-in-place-and-why-does-it-matter">CIP design: static spray balls rely entirely on volume to cover a tank surface, which wastes cleaning media and extends cycle times. The SB family uses a rotating head driven by flow energy alone, concentrating cleaning media into fan-shaped jets that trace a repeating swirling pattern throughout the tank. This converts the same flow rate into greater surface impact and broader wetting coverage — 360° full wetting as standard, with a 270° up pattern available for top-entry tanks where upward-only projection is needed.

Model selection by tank volume

Four distinct models span the 1–400 m³ range. The SaniMidget SB handles tanks from 1–15 m³, with a wetting radius up to 3 m and an impact cleaning radius up to 1.4 m at working pressures of 1–3 bar. The SaniMidget SB UltraPure covers the same tank and pressure range with a modified non-metallic specification — PEEK MG rather than PEEK 450G — to meet USP Class VI requirements and current good manufacturing practice documentation standards for biotech and pharmaceutical environments. The SaniMagnum SB scales to 5–50 m³, extending the wetting radius to 4.5 m and the impact cleaning radius to 2.4 m, with a recommended tank size of 23–68 m³. At the top of the range, the SaniMega SB covers 40–400 m³ tanks with a recommended tank size of 50–350 m³, reaching a wetting radius of 6 m and an impact cleaning radius of 3 m at working pressures of 1–4 bar.

Construction and material specification for CIP hygienic tank cleaning

All metallic components across the standard SB range are manufactured from AISI 316L stainless steel. Non-metallic parts are PEEK 450G, an FDA-compliant polymer per 21CFR§177 that tolerates operating temperatures up to 95 °C and ambient temperatures up to 150 °C. Surface finish is Ra 0.8 µm on the SaniMagnum SB and SaniMega SB; the SaniMidget SB and SaniMidget SB UltraPure specify Ra < 0.8 µm. The SaniMidget SB UltraPure substitutes PEEK MG, adding USP Class VI certification for pharmaceutical-grade applications. Lubrication across all models is provided by the cleaning media itself — no separate lubricant supply is required.

How flow rate and pressure relate to cleaning reach

Performance curves for each model plot flow rate (m³/h) and cleaning radius (m) against inlet pressure — 0–3 bar for SaniMidget and SaniMagnum, 0–4 bar for SaniMega. Clip-on versions consistently deliver a higher flow rate than equivalent weld-on installations: approximately 0.5 m³/h additional flow for the SaniMidget SB, 1.5 m³/h for the SaniMagnum SB, and 2 m³/h for the SaniMega SB. Recommended operating pressure for SaniMidget and SaniMagnum is 2 bar; SaniMega specifies 2–3 bar. Inlet pressure figures are taken immediately upstream of the unit, so pipeline pressure drop between pump and unit must be accounted for in system design. Performance testing for the family notes water temperature during testing at approximately 20 °C. The SaniMega SB also offers 360° High Flow and 270° High Flow configurations for applications requiring elevated throughput.

Qualification documentation for regulated processes

Standard qualification documentation — Q-doc — covers EN 1935/2004, EN 10204 type 3.1 inspection certificate, FDA declaration of conformity, GMP EC 2023/2006, EU 10/2011, ADI, and QC declarations. Material certificates are supplied as EN 10204 type 2.2. The SaniMidget SB UltraPure extends this package with a USP Class VI certificate and an expanded Q-doc+ FAT/SAT option that includes requirement specifications, design specifications with traceability matrix, factory acceptance test protocols incorporating IQ and OQ, and a site acceptance test protocol for end-user execution. ATEX approval under Directive 2014/34/EU applies to all models, rated Category 1 for installation in zone 0/20 with gas rating II 1G Ex h IIB 85 °C–175 °C Ga and dust rating II 1D Ex h IIIC T85 °C–T140 °C Da.
