Penstocks

1 Channel penstock

EKOguard PEN 1

Basic measures:

Application:

• For isolation, closing and decreasing wastewater/rainfall water flow in the channels
• On cutomer's request watertight penstocks for pressure on both sides of the penstock plate are made

Functional description:

• Penstock plate is placed inside the frame which is fixed in the concrete slot inside the concrete channel. After insertion in the slot, concrete is poured under penstock frame in order to ensure watertightness between the wall and the frame.
• Penstock plate sealing is done on three sides: both lateral sides of the frame and at the frame bottom.

Working principle:

• By rotating trapezoidal spindle, relative movement of bronze nut along the spindle is conducted. It also pulls the shutting plate along. Water freely flows through clear width that emerges after the penstock plate is lifted up, while the other part of the channel intersection is watertight. Sealing is achived with weoges located on the penstock plate and penstock frame.
• Spindle drive, used to lift up the penstock plate, can be simply manual with or without reducer (using hand wheel) or electrical drive installed at the penstock top.
• Operating principle: OPEN/CLOSED

2 Wall penstock

EKOguard PEN 3

Basic measures:

Application:

• For isolation, closing and decreasing wastewater/rainfall water flow on the walls with round and rectangular openings.
• On customer's request watertight penstocks for pressure on both sides of the penstock plate are made.

Functional description:

• When using wall penstock, the frame is tightened with anchoring screws to the finished concrete wall whose geometry mustn't deviate more than 3 mm in flatness, and has to be smooth to accomplish watertightness between rubber seal on the penstock frame and wall area
• Penstock plate sealing towards the frame is conducted along the whole clear width rim on the wall (penstock plate)

Working principle:

• By rotating trapezoidal spindle, relative movement of bronze nut along the spindle is conducted. It also pulls the shutting plate along. Water freely flows through clear width that emerges after the penstock plate is lifted up, while the other part of the channel intersection is watertight.
• Spindle drive, used to lift up the penstock plate, can be simply manual with or without reductor (using hand wheel) or electrical drive installed at the penstock top.

3 Regulating wall penstock

EKOguard PEN 5

Basic measures:

Application:

• For isolation, closing and decreasing wastewater/rainfall water flow on the walls with round and rectangular openings.
• On customer’s request watertight penstocks for pressure on both sides of the penstock plate are made

Functional description:

• When using wall penstock, the frame is tightened with anchoring screws to the finished concrete wall whose geometry mustn’t deviate more than 3 mm in flatness, and has to be smooth to accomplish watertightness between rubber seal on the penstock frame and wall area
• Penstock plate sealing towards the frame is conducted along the whole clear width rim on the wall (penstock plate)

Working principle:

• By rotating threaded spindle, relative movement of bronze nut along the spindle is conducted. It also pulls the shutting plate along. Water freely flows through clear width that emerges after the penstock plate is lifted up, while the other part of the channel intersection is watertight.
• Continuous sealing of the penstock plate throughout its entire height
• Operating principle: Regulation
• Spindle drive, used to lift up the penstock plate, can be simply manual with or without reductor (using hand wheel) or electrical drive installed at the penstock top.

Optional accessories:

• Penstock can be supplied with hand drive-reducer with hand wheel or electric motor drives on customer’s request. In case of electric motor drives, penstock is commonly supplied with basic EM drive without additional options.
• If any additional options are required, such as switch local-0-remote, buttons, position indicator, supporting electrical box etc., they should be specially asked for.
