 HP SERIES PERISTALTIC DOSING PUMP.

DESCRIPTION

KEMFEED is a proven design, quality produced peristaltic pump suitable for delivering a wide range of chemicals.

The pump is ideally suited to commercial installations where reliability and strength are of paramount importance.

Typical applications are swimming pools, spas, cooling towers, sewerage treatment and aquaculture.

The pump can be specified with or without an integrated timer, to suit various applications.

There are twelve models in the range, offering a broad span of dose rates. Delivery pressures are between 400 & 600 kpa depending on pump tube size and gearbox RPM.

CO2 FLOW CONTROL

The KEMFEED CO2 Flow Control is designed to operate in conjunction with any proprietary chemical controller and is constructed using only quality components.

The unit is flow adjustable and suitable for fitment to most spas and pools up to 1000 cubic metres volume.

Three injector / piping systems are available.

• Noryl saddles to suit 50, 80, 100 and 150 mm PVC pipe. Saddles are convenient for fitment to installations where it is difficult to cut into existing pipe work..
• PVC Tees in 50, 80, 100 and 150 mm for new installations. Tees are fitted with a quick release 50 mm barrel union to allow for easy inspection of the injector assembly. 
• Injector assembly with 1inch BSP male thread. Screws direct into tapped pipes or fittings.

Installation is simple, with all necessary hardware, tubing and fittings included.

Kemfeed is a robust reliable unit that requires a minimum of maintenance. Replacement parts are readily available and can be fitted by pool industry service personnel.

OPERATION.

When the chemical controller senses a required pH adjustment, the controller output signal energises the CO2 flow control solenoid which is connected to CO2 bottle regulator pressure. CO2 gas flows through the  solenoid, flow meter and non return valve direct into the water stream via the diffuser.

Injectors are normally fitted down stream of all other components in the return to pool line, however if preferred they can be fitted prior to the filter.

A percentage timer can be fitted to the flow control to provide adjustable on / off dose for applications where the controller has no internal timing, or no controller is in use.
