TAM-6-138

Mechanical Diaphragm Dosing Pump 310 L / Hour at 7.0 Bar

Mechanical Diaphragm Dosing Pump TAM-4-108 with PolyPropylene head

TAM-6-138 Mechanical Diaphragm Dosing Pump pictured here with a PolyPropylene head, is available with a choice of 3 gearbox sizes.

TAM-6-138 Mechanical Diaphragm Dosing Pump Introduction

The TAM-6-138 Mechanical Diaphragm Dosing Pump has works on a cavity displacement principle with a reciprocating PTFE diaphragm, causing a linear volumetric displacement to enable steady, even and continuous chemical metering.

As a process device, the TAM-6-138 is designed to deliver defined amounts of chemical reagent with high precision. Manufactured with an aluminium body and foot mounting stand, the TAM-6-138 is designed to be horizontally mounted and connected to a process using 3/4" BSP connections, or 1" BSP connections. (1" BSP connections are on the TAM-6-138-116 only).

The TAM-6-138 is driven from a 3 phase 0.37kW 400V AC motor and is also available with a single phase 0.55kW 230V AC motor.


TAM-6-138 Mechanical Diaphragm Dosing Pump Head Options

The TAM-6-138 Dosing Pump is available with a choice of four head material types, inlcluding: PolyPropylene, PVC, PVDF or 316 Stainless Steel.  All the head options on the TAM-6-138 are paired with a PTFE diaphragm measuring 138mm Ø. The stroke length of the TAM-6 series is 6mm.

As well as the head material, the other liquid end components (otherwise known as wetted parts) which constitute the materials in contact with the solution to be dosed, are available in a range of materials to provide greater compatibility with a range of chemicals.

Head MaterialDiaphragm MaterialSeal MaterialBall Valve MaterialValve Seat MaterialConnections
Polypropylene PTFE N/A Ceramic / PTFE N/A 3/4" BSP / 1" BSP
PVC PTFE N/A Ceramic / PTFE N/A 3/4" BSP / 1" BSP
PVDF PTFE N/A Ceramic / PTFE N/A 3/4" BSP / 1" BSP
Stainless Steel PTFE 316 Stainless Steel 316 Stainless Steel 316 Stainless Steel 3/4" BSP / 1" BSP

The TAM-6-138 has either 3/4" or 1" BSP connections, depending upon the number of strokes per minute that the pump makes.  Unlike the smaller TAM-2 and TAM-4 series of mechanical diaphragm dosing pumps, the TAM-6-138 doesn't have any seals or O-rings in contact with the chemical to be dosed.

The TAM-6-138 uses a double ball valve for both the suction side and discharge side of the pump to aid both priming of the pump and to ensure precision chemical delivery during operation.

You can check the material compatibility using our material compatibility database and we also recommend that you check with your chemical supplier to ensure that all the parts of the liquid end are compatible with the chemical to be dosed.


TAM-6-138 Gear Box Options

As with all the pumps in our TAP range, the TAM-6-138 is available with a fixed speed gear box to give either 58 stokes per minute, 78 strokes per minute or 116 strokes per minute.

By increasing the number of strokes per minute, the output flow rate of the pump changes as per the following table:-

Model NumberStrokes / MinuteFlow (L/Hr)Pressure (Bar)*Connections
TAM-6-138-58 58 0 - 155.0 7.0 3/4" BSP
TAM-6-138-78 78 0 - 220.0 7.0 3/4" BSP
TAM-6-138-116 116 0 - 310.0 7.0 1" BSP

Mechanical Diaphragm Dosing Pump Adjustable Flow Rate

The TAM-6-138 has a micrometer stroke length adjustment dial mounted at the side of the pump.  This allows the stroke length to be reduced from the maximum length of 6mm so that the flow rate can be set to anywhere between 0 - 100% of the strokes maximum output. To maintain accuracy, we don't advocate running the pump below 20% of the rated output.


TAM-6-138 Features & Benefits

The TAM-6-138 Mechanical Diaphragm dosing pump is a foot mounting mechanical diaphragm dosing pump designed to be secured on a horizontal surface to deliver a chemical reagent to a process.

With a choice of 316 Stainless Steel, PolyPropylene, PVC, or PVDF head materials, all combined with a PTFE diaphragm and no valve seals or O-rings, the TAM-6-138 is compatible with a wide range of chemical reagents, including concentrated chemicals.  Please don't hesitate to contact us or check with your chemical supplier to ensure compatibility with your process.

With a PTFE diaphragm and accurately machined and assembled components, the TAM-6-138 is designed to meter a defined volume of chemical, steadily and evenly, into a process with high precision.

The TAM-6-138 can be fitted with either a 0.37kW 3 phase 415 VAC motor or a 0.55kW 3 phase 230 VAC motor.

Each motor drives a gearbox with outputs of 58, 78, or 116 strokes per minute and 155.0 Litres / Hour, 220.0 Litres / Hour, or 310.0 Litres / Hour respectively.  Each option has a maximum pressure output of 7.0 Bar when using with any combination of head materials.  All the head options use 3/4" BSP connections for easy connecting, directly into a process.

With a micrometer adjustment, the output rate of the pump can be user adjusted between 0 - 100% of the flow rate to give greater control over your chemical dosing.

The TAM-6-138 is fully compatible with a range of dosing accessories including: pulsation dampeners, anti-syphon, back pressure and safety valves.
