Three Static Mixer Series. Every Application.

From low-viscosity water treatment to high-viscosity polymer melts, the Primetech range covers the full spectrum of inline mixing duties.

KE Series
KE Helical Element Static Mixer

Kenics-equivalent design. Each 180° helical element is joined at 90° to the next, alternating RH and LH rotation. The leading edge of each element bisects the trailing edge of the preceding one, halving striation thickness per element. Covers the full Reynolds Number range from deep laminar to fully turbulent. The standard choice for chemical dosing, pH control and heat transfer.

Size rangeDN25 – DN600
Flow regimeLaminar to turbulent
Elements4 – 21 per unit
Pressure dropK = 2.0 per element
KE Series
SX Series
SX Cross-Bar Static Mixer

Sulzer SMX-equivalent design. Corrugated bar lattice at ±45° creates a three-dimensional grid. Number of striations grows as 2N, giving exponential homogenisation. Handles viscosity ratios up to 1,000,000:1. Deep laminar service only (Re < 500). Preferred for polymer melt blending, two-component adhesives and colour masterbatch.

Size rangeDN10 – DN300
Flow regimeDeep Laminar (Re < 500 — SMX geometry)
Elements8 – 24 per unit
Viscosity ratioUp to 1,000,000:1
SX Series
VN Series
VN LPD Vane Static Mixer

Open LPD vane geometry for large-bore turbulent service. Tolerates slurries, fibrous media and two-phase flow without plugging. Lowest pressure drop of any Primetech mixer — preferred for water treatment mains and pipeline blending.

Size rangeDN100 – DN1200
Flow regimeTurbulent only (Re > 10,000)

THREE SERIES.
EVERY DUTY.

Helical element, cross-bar and LPD vane — each series optimised for a specific operating regime.

KE Series

Helical Element

Kenics-equivalent design. Each element is a 180° helical twist of a flat plate, spanning the full pipe bore. Successive elements are joined at 90° to the previous, alternating right-hand (RH) and left-hand (LH) rotation. The leading edge of each element bisects the trailing edge of the previous, splitting the fluid radially and rotating it 180° before the next split. This geometric progression halves the striation thickness with every element. Effective across the complete Reynolds Number range from deep laminar (Re < 10) to fully turbulent (Re > 10,000).

SX Series

Cross-Bar Mixer

Sulzer SMX-equivalent design. Each element is a corrugated metal lattice of bars arranged at ±45° to the pipe axis, with successive layers crossing each other to form an open three-dimensional grid. Fluid is repeatedly split, cross-mixed and recombined at every bar intersection. Because every crossing is a new split-and-recombine event, the number of striations grows as 2N (where N is element count), giving extremely rapid homogenisation at high viscosity ratios. Limited to deep laminar service (Re < 500); pressure drop is approximately 38× the equivalent Hagen-Poiseuille loss per element length.

LPD Vane Mixer

Ross LPD-equivalent design. Each stage carries one right-hand (RH) semi-circular vane and one left-hand (LH) semi-circular vane mounted on a central stiffener rod that runs the full mixer length. The two vanes span the pipe bore and deflect fluid into counter-rotating swirl zones. Successive stages are offset 90° to re-orient the swirl pattern, stripping the boundary layer and redistributing fluid radially. The open geometry (no transverse obstructions) passes slurries, fibrous media and two-phase flows without clogging. At K=0.7 per stage the VN is the lowest pressure-drop mixer in the Primetech range, delivering CoV ≤0.05 in six stages for Re > 10,000.

Turbulent ΔP — K=0.7 per stage (Ross LPD equivalent), ρ=1000 kg/m³. Approximately 65% lower ΔP than KE at equivalent stages and velocity. Formula: ΔP (mbar) = N×0.7×ρV²/2 ÷100.
