  • The equipment STS-45 with the gerotor type pump for the glass-fiber reinforced concrete (GFRC) production

    The equipment for the glass-fiber reinforced concrete with the gerotor (screw) pump, issued for GFRC items production by sputtering technique in workshop conditions or protective finish on-site (reinforcing to 7%). For sputtering or pouring premix we recommend to use the equipment for GFRC with the peristaltic pump.

    The grout pump PN SFBUM4 is a part of production comlpex of GFRC items, consisted of the gerotor pump, including the charging hopper over it, which provides a cement-sand grout delivery with the specified productivity to the mixing unit with the fiber and sputtering by concrete gun (type RPN).

    GFRC production. The complex STS-45 with the gerotor pump.

    The grout pump (type SFBUM4) builds up a pressure to 2 megapascals and handles the concrete composition to GFRC spraying gun. Device consists of the following parts: a screw pump, electrical facilities, a charging hopper, a gear system, a mount. It's apt to do pumping capacity regulation (to 12 kg/min), what is the most important during GFRC items production, because it allows to dimension the flame body size directly according to the concrete form. A small form, a difficult pattern mean delivery decrease. A giant form, a smooth relief mean delivery increase.

    The grout pump SFBUM4 is an additionally supplied with the central control board – PUV-3. Inside the body there are erected the oil holder and the oil-and-moisture separator, also output the panel of pressure-sensitive detector and the gages. There is no need to organize an air distributing from the compressor. A machineman’ aim is only the air supply to PUV-3, which has 3 outputs. Thus, a machineman has a possibility to monitor and control the air distributing on all technological levels of GFRC' production.

    The grout pump' mandatory attribute is a jigger screen, which guarantees the quality of the mix and protects RPN spraying gun from stones and different undesirable elements.
