The H.C.2A and H.C.3A Spray Pump Units are robust, medium and high output spray systems designed for pumping an accurately controlled quantity of cement slurry under the most arduous conditions for the productions of Glassfibre Reinforced Cement by simultaneous spray.
They have a 250Kg large capacity hopper with vibrated sieve, feeding a progressive cavity pump driven by a hydrostatic gearbox with manual speed control.
The H.C.2A output is up to 20Kgs per minute and is usually used for handspray with either PII Concentric or MKII Twinhead spraygun while the H.C.3A has an output of up to 5OKgs per minute which is more than sufficient for the P3 Concentric spraygun or high output auto sprayguns.
The H.C.3A can also be used to pump to the PII Concentric or MKII Twinhead sprayguns where the effect of running a high-output pump at low-speed and output is to ensure that the rotor and stator has a much-extended (and therefore economical) life when compared with the low-output pump run at high speed.
The control box contains all necessary electrical controls while the pneumatic controls are mounted on the pillar beneath. During spraying the pump is controlled by a sensitive flow switch that is unaffected by pressure changes, while for setting up and cleaning purposes the pump is controlled from the panel.
The H.C.2A and H.C.3A machines are built on strong chassis' with heavy duty castors for easy mobility and the pump is readily accessible for maintenance.
