1 TECHNICAL DESCRIPTION
1.1 PRODUCT NAME AND FEATURES
The subject of this O&MM is:
Cast-iron standpost hydrant TYPES 8001 and 8010 with automatic water drainage activated by flow
stoppage.
1.2 PURPOSE
The cast-iron standpost hydrants TYPES 8001 and 8010 with automatic drainage are designed for
installation on underground pipelines laid horizontally below the freezing zone, and are intended for
drawing water.
1.3 TECHNICAL SPECIFICATION
Cast-iron standpost hydrant TYPES 8001 and 8010 with automatic water drainage is designed for
drawing water at temperatures from +1°C to +50°C.
- Available diameters (dimensions) ¾”
- Maximum medium flow rate: - Liquid up to 4 [m/s]
- Equipment control: by pressing a lever.
2 STRUCTURE
2.1 FITTING DESIGN DESCRIPTION
A cast-iron standpost hydrant TYPES 8001 and 8010 with automatic water drainage includes a cast-iron
body and head placed above ground and an underground valve chamber with connection, attached to the body
with a column with flange located on the hydrant's foot. The hydrant's foot is placed on the ground above water
supply network's pipe. The valve chamber contains a closing component (a poppet valve) connected to the outlet
in the upper part of the hydrant using a suction pipe also used for drawing water. The movable suction pipe inside
the hydrant's top part is coupled with control lever via stopped used for closing the vertical section of the suction
pipe supported with a spring. The spring presses the suction pipe to the valve chamber seat. Pressing the lever
attached axially inside the hydrant's top part lifts the complete suction pipe and opens water flow. After releasing
the lever, the spring pushes the suction pipe downwards and closes water flow. The valve chamber has a seal for
the closing component which cuts off the coupling with the column when the suction pipe is raised (open flow)
and opens the connection of the suction pipe with the column with suction pipe lowered (closed flow), thus
enabling the remaining water from the suction pipe flow to the column. That way, fresh water does not enter the
column and after every draw the remaining water flows to the space located between the column and the suction
pipe and it may escape to the ground through the water drainage outlet connection.

3 PROTECTION, STORAGE & TRANSPORT
3.1 PROTECTIVE COATINGS
All inner and outer cast-iron surfaces and column pipes are protected with electro-deposited epoxy coat. The
coat has been approved for contact with foodstuffs.
The anti-corrosion coating layer minimum thickness is 250µm, with UV protection.
The casting surface is pre-treated for epoxy coating in accordance with the relevant technical documentation and
standard PN-EN ISO 12944-5: 2009.
The fastening bolts for external hydrant's part, if other than stainless steel grade 1.4301, should
have corrosion protection in the form of coat, e.g. Fe/Zn5.
3.2 PACKAGING
The standpoint hydrants are placed in plastic film sleeves and additionally wrapped with stretch wrap when
placed on pallets.
3.3 STORAGE
Hydrants should be stored in covered areas.

4 ASSEMBLY AND INSTALLATION
4.1 INSTALLATION GUIDELINES
Hydrants may be installed on underground pipelines on horizontal systems. The product described
herein is designed for installation using flange on the pipeline acting as medium (water) supply.
Note that the system must not expose the hydrant to bending or tensile stress from loading with the unsupported
pipeline sections. A hydrant assembled and adjusted by the manufacturer is ready for installation in the system.
Any dismantling of the hydrant components may result in loss of tightness.
4.2 INSTALLATION INSTRUCTIONS
Before installing the hydrants, check the technical and commercial documentation, i.e. application for
media and operation parameters of the pipeline, in which they are to be installed.
Note! If the product is damaged mechanically, do not install it in the pipeline.
Any change in the operating conditions must be consulted with the hydrant's manufacturer beforehand.
1. — hydrant, 2. — seal, 3. — pipeline connecting flange, 4. — pipeline
