| in all stainless steel - with channel impeller |
|
The submersible, high efficiency channel impeller pumps in all stainless steel are used for applications where chemical resistance is required in combination with some solids handling. The solids handling is much better than for traditional drainage pumps. These channel pumps are very suitable for applications in a.o. agricultural, com-posting and general industry. The base material is stainless steel AISI 316 or duplex stainless steel AISI 329.
|
| 3 Different hydraulic designs:
Highest efficiencies, better solids handling or highest heads. | | | | | Much wider solids handling up to 30 x 50 mm,
compared with traditional drainage pumps. | | | | | Available in all stainless steel AISI 316 | | | | | And in duplex stainless steel AISI 329,
for increased durability in sea water and chloride based liquids | | | | | High quality casted parts, not pressed stainless steel. | | | | | Fully serviceable pumps | | | | | Most models are available in certified explosion proof version | | | | | Warm liquid versions available up to 80oC
|
|
| Highest efficiencies:
The 3-bladed impeller combines highest efficiency with good free passage; 30x30 mm.
Due to it's symmetrical shape the triple channel impeller is less sensitive for vibrations due to wear.
|
|
|
|
|
| Best solids handling:
The single leading edge of this impeller type proved to be much better for handling fibrous materials. In addition the free passage of 30x50 mm is much wider.
The steep QH curve provides a stable output.
|
|
|
|
|
| Highest heads:
The 6-bladed centrifugal impeller generates highest heads. These pumps come standard with a strainer with 8 mm openings. This is slightly smaller than the actual through let of the impeller.

| Base material AISI 316 stainless steel
The base material for all parts is stainless steel AISI 316. This is an austenitic stainless steel that outperforms the cheaper AISI 304 material as often used in pumps. | | | | | Base material AISI 329 duplex stainless steel
In the chemical process industries the use of duplex stainless steels is increasing rapidly. Duplex stainless steel is better re-sistant against pitting in chloride based environments and in sa-line and sea water. It is also better wear resistant than AISI 316. This material can also be used at lower pH's. | | | | | Increase wear resistance
For applications where increased abrasion resistance is re-quired the standard AISI 316 pump with impeller and wear liner in duplex is a good alternative. In more demanding applications it's possible to supply the volute/seal housing in duplex too.

|
| Bolts, nuts and shaft and related parts
The standard material is AISI 316.
Upon order these parts are also available in AISI 329. | | | | | Pump side shaft seal
The mechanical seal is a rubber bellows type with seal faces from sintered silicon carbide. This material is better suitable for most chemicals.
The rubber parts are in Viton (FPM) or option-ally in EPDM or KALREZ.
The metal parts are in AISI 316Ti. | | | | | Elastomers
Both the AISI 316 and AISI 329 pumps come standard with Viton (FPM) elastomers.
As an alternative Teflon coated or EPDM O-rings can be supplied. | | | | | Cables
The SubCab cable, specially developed for underwater use, is with an outer sheet from oil resistant and flame retardant chlorinated polyethylene. Upon demand a HCR (heat and chemical resistant) cable in Fluor ethylene propylene is available. The most widely used option is a flexible stainless steel protection sheath in AISI 316Ti that hermetically seals the cable from the medium.

Warm liquid versions
In basic version the pumps are suitable for 40oC liquid temperatures. Upon demand warm liquid versions are available for temperatures up to 80oC.
|
Explosion proof
Many models are available in ATEX or FM certified explosion proof version.
|
Installation options
All pumps are with integral support feet. With one of the many threaded and hose adapters they are suit-able for transportable or semi-permanent freestanding installation.
For permanent installations we have our guide rail type quick release couplings in AISI 316 and AISI 329.
