TAM-2-94 Mechanical Diaphragm Dosing Pump pictured herewith a PVDF head, available with a choice of 3 gearbox sizes.

TAM-2-94 Mechanical Diaphragm Dosing Pump Introduction

The TAM-2-94 Mechanical Diaphragm Dosing Pump works on a cavity displacement principle with a reciprocating PTFE diaphragm causing a linear volumetric displacement which enables steady, even and continuous chemical metering.

As a process device, the TAM-2-94 is designed to deliver defined amounts of chemical reagents with high precision. Manufactured with an aluminium body and foot mounting stand, the TAM-2-94 is designed to be horizontally mounted and connected to a process using the 3/8" BSP connections.

The TAM-2-94 is driven from a 3 phase 0.25kW 400VAC motor and is also available with a single phase 0.37kW 230VAC motor.

TAM-2-94 Mechanical Diaphragm Dosing Pump Head Options

The TAM-2-94 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-2-94 are paired with a PTFE diaphragm measuring 94mm Ø.  The stroke length of the TAM-2 series is 2mm.

As well as the head material the other liquid end components (otherwise known as wetted parts) which constitutes the materials in contact with the solution to be dosed are available in optional materials to provide greater compatibility with a range of chemicals and the wetted parts are listed below:-

Head MaterialDiaphragm MaterialSeal MaterialBall Valve MaterialValve Seat MaterialConnections
Polypropylene PTFE Viton / EPDM Ceramic / PTFE PTFE 3/8" BSP
PVC PTFE Viton / EPDM Ceramic / PTFE PTFE 3/8" BSP
PVDF PTFE Viton / EPDM Ceramic / PTFE PTFE 3/8" BSP
Stainless Steel PTFE 316 Stainless Steel 316 Stainless Steel 316 Stainless Steel 3/8" BSP

The TAM-2-94 makes use of 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 there is precision chemical delivery during operation.

The valve seats are available in either Viton (© DuPont / Chemours) or EPDM.  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-2-94 Gear Box Options

As with all the pumps in our TAP range, the TAM-2-94 is available with a fixed speed gear box to give either 58 strokes 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-2-94-58 58 0 - 20.0 10.0 3/8" BSP
TAM-2-94-78 78 0 - 26.0 10.0 3/8" BSP
TAM-2-94-116 116 0 - 40.0 10.0 3/8" BSP

* High pressure 16.0 Bar version is available in models with a PVC head.

Mechanical Diaphragm Dosing Pump Adjustable Flow Rate

The TAM-2-94 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 2mm 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-2-94 Features & Benefits

The TAM-2-94 Mechanical Diaphragm dosing pump is a foot mounting mechanical diaphragm dosing pump designed to be secured a horizontal surface to deliver a chemical reagent to a process.

With a wide range of wetted parts available, the TAM-2-94 is suitable for operation with a wide range of chemical reagents, including concentrated chemicals.  Please don't hesitate to contact us for advice or check with your chemical supplier to ensure compatibility with your process.

With a PTFE diaphragm and accurately machined and assembled components, the TAM-2-94 is designed to meter a defined volume of chemical, steadily and evenly into a process, with high precision.

The TAM-2-94 can be fitted with either a 0.25kW 3 phase 415 VAC motor or a 0.37kW 3 phase 230 VAC motor.

Each motor drives a gearbox which either outputs 58, 78, or 116 strokes per minute and 20.0 Litres / Hour, 26.0 Litres / Hour, or 40.0 Litres / Hour, respectively.  Each option has a maximum pressure output of 10.0 Bar when using with any combination of head materials.  A high pressure 16.0 Bar PVC head is also available.  All the head options use 3/8" 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-2-94 is a fully compatible with a range of dosing accessories, including: pulsation dampeners, anti-syphon, back pressure and safety valves.
