Piston Dosing Pump 22 L / Hour at 20.0 Bar

TAP15-17 Piston Dosing Pump available with a choice of 3 gearbox sizes and either Stainless Steel or PVC head materials.

TAP15-17 Piston Dosing Pump Introduction

The TAP15-17 Piston Dosing Pump works on a cavity displacement principle with a reciprocating piston causing a linear volumetric displacement, enabling steady, even and continuous chemical metering.

As a process device the TAP15-17 is designed to deliver a defined amount of chemical reagent, with high precision. Manufactured with an aluminium body and foot mounting stand, the TAP15-17 is designed to be horizontally mounted and connected to a process using the 3/8" BSP connections.

The TAP15-17 is driven from a 3 phase 0.18kW 400VAC motor and is also available with a single phase 0.25kW 230VAC motor.

TAP15-17 Piston Dosing Pump Head Options

The TAP15-17 Dosing Pump is available with a choice of two head material types, either all manufactured in 316 Stainless Steel or manufactured in PVC with a ceramic piston.  The piston has a 15mm stroke length and a diameter of 17mm.

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 choice of materials to provide greater compatibility with a range of chemicals.  The wetted parts corresponding to the head material are listed below:- 

The TAP15-17 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 precision chemical delivery, during operation.

The valve seats are available in either EPDM or Viton (© DuPont / Chemours) and we recommend checking our chemical compatibility database and your chemical supplier to ensure that all the parts of the liquid end are compatible with the chemical to be dosed.

TAP15-17 Gear Box Options

As with all the pumps in our TAP range, the TAP15-17 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:-

Piston Dosing Pump Adjustable Flow Rate

The TAP15-17 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 15mm so that it can be set anywhere between 0 - 100% of the strokes full output.  To maintain accuracy, we don't advocate running the pump below 20% of the rated output.

TAP15-17 Features & Benefits

The TAP15-17 piston dosing pump is a foot mounting piston dosing pump, designed to be secured onto a horizontal surface to deliver a chemical reagent to a process.  With accurately machined and assembled components the TAP15-17 is designed to meter a defined volume of chemical, steadily and evenly into a process, with high precision.

The TAP15-17 can be fitted with either a 0.18kW 3 phase 415 VAC motor or a 0.25kW 3 phase 230 VAC motor.

Each motor drives a gearbox which either outputs 58. 78, or 116 strokes per minute with an output of 11.0 Litres / Hour, 15.0 Litres / Hour, or 22.0 Litres / Hour respectively. Each option has a maximum pressure output of 20.0 Bar when using a 316 Stainless Steel Head or 10.0 Bar with the head material in PVC.  Both options have 3/8" BSP connections for easy connecting directly into a process.

The TAP15-38 includes a range of options for the liquid end or wetted parts, including options for 316 Stainless Steel, or PVC with a ceramic piston and either Viton or EPDM seals / O-rings.

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 TAP15-17 is fully compatible with a choice of dosing accessories including: pulsation dampeners, anti-syphon, back pressure and safety valves.
