Sieve bend filters

Holland Filter develops and manufactures sieve bends in its own Susteren workshop. We design stainless steel systems to separate solids from process water and wastewater, considering flow, contamination and available installation space.

Sieve bends are used in horticulture, meat processing and industrial water treatment. They remove large quantities of relatively coarse contamination. Different models and designs support varied capacities and cleaning needs.

Standard model or project-specific design

We work directly with engineering firms, plant builders, OEM partners and resellers. Do you have an idea, drawing or technical challenge? Together we determine a technically and economically suitable design. Our own design and manufacturing enable custom solutions.

How sieve bend filtration works

Holland Filter sieve bends are often used to filter coarse particles larger than 0,25 mm.

The static or dynamic screen retains solids on its surface, separating them from the liquid.

Liquid falls through the screen with a self-cleaning effect. Solids slide down the curved screen and fall into the waste container below.

Filtration technology

The triangular wires are mounted at a slight angle, cutting the downward water flow.

These sharp edges should also be perceptible to the fingers in the downward direction.

Sieve bends are supplied in stainless steel AISI 304. Screen opening varies from 10 to 3000 micron (to be determined).

Sieve bend benefits

1 Continuous flow
Liquid continues to flow throughout filtration without interrupting the process.

2 Automatic cleaning cycle
The downward water flow carries filter waste directly into the container below.

3 Low maintenance
Screens are made of stainless steel 304/316-L and require no mechanical cleaning, making them low-maintenance.

4 No filter aids
Screens filter without additional cloth or filter aid.

Sieve bend designs

Siebostatic model

The standard sieve bend is a self-cleaning system.

Flow over the screen washes remaining dirt down into the collection trough or waste container.

These sieve bends are often used in industry or horticulture for dust, sand and easily washed particles.

Siebomatic model + spraysystem

These sieve bends have an additional spray system at the front above the screen.

If excessive dirt blocks the screen, the spray system uses additional water force to dislodge particles and discharge them downwards.

This design is commonly used for water filtration in vegetable, meat and fish processing.

Viebomatic + vibrationmechanism + spray system

A vibration mechanism and spray system at the front above the screen simultaneously loosen particles, which fall into the waste container.

These sieve bends are mainly used in meat and fish processing.

Sieve bend models

Model M:Compact series

Small sieve bends for low flow rates

The M sieve bend is a compact design for places where the height of a standard sieve bend will not fit.

Model M specifications:

Type 250M-500M-750M-1000M-2000M 

The M type is made of 2mm stainless steel sheet, with a one-piece cover and a closed height of only 650 mm.

Model M options:

Standard stainless steel 304 with cover and 2 flanges.

Stainless steel 316 is optional.

Additional frame

If needed, mount higher on a frame with a discharge hopper and waste container.

Model H-Q-S-X:

Largest series for highest flow rates

Benefits

– multiple savings at higher flow rates

– less floor space for one filter instead of two or more

– lower overall project investment

Specifications

HF1800H – HF1800Q – HF2200Q – HF2300X

These sieve bends are made of 3mm stainless steel sheet with a single cover, sloping bottom and larger bottom and overflow tanks.

Configuration options

Standard stainless steel 304 with cover and 2 flanges.

Stainless steel 316 Stainless steel 316 is optional.

FrameIf required, the sieve bend can be mounted higher on a frame with a discharge hopper and waste container.

Model T:

With vibration mechanism

For better removal of dirt and biological particles from the screen in meat, fish and vegetable processing.

T sieve bends are suited to difficult wastewater containing dust, sand and biological particles from slaughter and vegetable/fruit waste. Vibration prevents particles adhering to the screen and improves their flow into the waste container.

Model T specificationsHF400-HF800-HF1200-HF1800-HF2200

The T type is made of 3mm stainless steel sheet and supplied as standard in stainless steel 304 with vibration motor, air unit, cover and 2 flanges.

Stainless steel 316 is optional.

If needed, mount higher on a frame with a discharge hopper and waste container.

Drain container:

DC25-DC50-DC75-DC100

Standard configuration:
250 – 500 – 750 – 1000 litre models

• Stainless steel 304
