A Fluimac Phoenix model code looks like a random string of letters and numbers at first glance. It isn’t. Every character specifies something — pump series, size, casing material, diaphragm material, ball material, seat material, o-ring material, connection type, and ATEX zone. If you’re ordering a replacement, requesting a quote, or trying to identify a pump already installed in your facility, knowing how to read the code means you can extract all of that information from the label without calling anyone.
The Code Structure
A full Phoenix model code reads left to right across eight fields, separated visually by the structure of the code itself. Using the example from the manual — P0030A-HTTAT1-AB — here’s what each element means:
Field 1: Pump Series
The first letter or letter combination identifies the pump series:
P = Phoenix (standard)
PF = Phoenix Food (FDA-compliant materials, for food-contact duty)
AP = Accurate Phoenix
TP = Twin Phoenix
PP = Powder Phoenix
SP = Submersible Phoenix
For most industrial and chemical applications, you’ll be working with a standard P or a PF for food-grade duty.
Field 2: Size
The number following the series prefix is the pump size: 3, 7, 18, 30, 50, 55, 60, 65, 90, 100, 101, 120, 160, 170, 171, 250, 252, 400, 700, or 1000. This number corresponds to the approximate maximum flow rate class and determines the port size, diaphragm diameter, and solid-passing rating. The P30 handles up to 35 L/min; the P1000 handles up to 1,050 L/min.
Field 3: Pump Casing Material
This single letter or letter combination specifies what the main pump body and manifolds are made from:
P = PP (polypropylene)
PC = PP + carbon fibre fill (conductive grade)
KC = PVDF + carbon fibre fill (conductive grade)
O = POMc (acetal copolymer)
OC = POMc + carbon fibre fill
A = Aluminium
S = SS AISI 316
Casing material determines chemical compatibility, temperature range, and ATEX group. Smaller models (P3–P120) in IIC-rated ATEX zones use PP, PVDF, Acetal, or SS316. Larger models (P160–P1000) are rated IIB — a slightly less restrictive gas group classification. Material selection is the single biggest factor in pump suitability for a given chemical.
Field 4: Diaphragm Material
N = NBR (nitrile rubber)
D = EPDM
T = PTFE
H = Hytrel
S = Santoprene
The diaphragm is the component in direct contact with the process fluid on the fluid side, and with air on the air side. PTFE is the standard choice for aggressive chemicals — acids, solvents, oxidisers. EPDM suits aqueous solutions and some dilute acids. NBR suits petroleum-based fluids. Hytrel and Santoprene occupy a middle ground for moderate chemical exposure combined with good flexibility at low temperatures.
Field 5: Ball Material
N = NBR
D = EPDM
T = PTFE
S = SS316
P = PP
K = PVDF
A = Aluminium
Z = PE
O = POMc (Acetal)
The ball check valves seal the suction and delivery manifolds on each stroke. Ball material must be chemically compatible with the process fluid. SS316 balls are used in abrasive or high-temperature service. PTFE balls suit aggressive chemicals. PP and PVDF suit many aqueous acid and alkali applications.
Field 6: Ball Seat Material
V = Viton
D = EPDM
N = NBR
T = PTFE
The seat is the mating surface the ball seals against. It’s typically softer than the ball to ensure a good seal — the seat conforms slightly to the ball surface. Seat material must match the ball material in terms of chemical compatibility, but is often different to provide the right hardness combination.
Field 7: Connection Type
1 = BSP (British Standard Pipe, parallel thread)
2 = Flanged
3 = Tri-Clamp (Phoenix Food only)
5 = NPT (American tapered thread)
6 = BIN 11851/3 (Phoenix Food only)
For Malaysian and regional installations, BSP is the most common. NPT is specified where US-standard piping is in use. Tri-Clamp and BIN connections are hygienic fittings for food and pharmaceutical duty.
Field 8: ATEX Certification
– (hyphen) = ATEX Zone 2
X = ATEX Zone 1
Zone 2 is the standard ATEX rating for most Phoenix pumps. Zone 1 (X suffix) indicates the pump is rated for environments where explosive atmospheres are present continuously or frequently — a higher certification level requiring additional design controls.
Putting It Together
A code like P0030A-HTTAT1-AB decodes as: Phoenix series, size 30, Aluminium casing, Hytrel diaphragm, PTFE balls, PTFE seats, BSP connections, Zone 2 ATEX. That’s a 35 L/min pump in aluminium body with full PTFE wetted path — suited for moderate chemical service requiring good chemical resistance without going to PVDF.
When ordering spares, the model code tells you which diaphragm part number applies, which ball and seat kit to order, and which maintenance procedure applies based on the model group size.
