WD: these types of pumps are equipped with WD (water detector – moisture sensor of leakage) in standard.
(F) in type marking means pump is equipped with float switch.
* Voltage-phase :
1F – one-phase – 1 + PE230V
Č
SN EN 60204-1
3 F – three-phase – 3 + c PE 400V
** Solid passage: diameter of solid particles that can get through the pump without clogging the impeller.
*** Depend on used discharge connection and hose.
4.0 TECHNICAL DESCRIPTION OF PUMPS
HCP submersible sludge pumps are one-stage pumps designed for various loads and types of operation.
4.0.1
AF – designed for maximum loads and permanent operation. Four types of impeller wheels are used:
P-TYPE IMPELLER: Single-blade or double-blade semi-open impeller.
U-TYPE IMPELLER: Vortex impeller enables pumping media containing solid particles and long-fibre
substances without going through the impeller. The impellers have good resistance against clogging.
E-TYPE IMPELLER: Closed, one-channel two-blade impeller characteristic for great delivery height. Very
efficient for pumping waste waters containing solid particles.
4.0.2
AL, BF - portable sludge pumps with open impellers, either single-blade (P) or multi-blade (U-vortex),
depending on type.
4.0.3
SS, SF – stainless-steel portable one-stage pumps designed for pumping aggressive waste waters. The
impellers are open, either single-blade (P) or multi-blade (U-vortex), depending on type.
4.0.4
AS, AG – portable sludge pumps with multi-blade impeller made from a special alloy with high content of
chrome (HCR). Having been heat-processed, this alloy is very hard and resistant against abrasion.
Pumps ASH and AGH has open impeller, and pumps ASN, ASL, AGN has closed channel impeller.
Pumps AG series is eqipped with cast iron agitator fitted on extended shaft to create powerfull stirring opositte
botom of reservoir and pumping action for slurry.
4.0.5
IC – portable one-stage pumps with closed multi-channel impeller. Type 50ICA21.1 impeller is made of
bronze, other types from chrome steel.
4.0.6
GD, GDR – portable one-stage pumps with open, multi-blade impeller. Impeller and casing are made of
special rubber with high abrasion resistance. GDR pumps have a special suction pad allowing the drawdown
water to the level of 2mm.
4.0.7
GF – portable one-stage pumps fitted with open, multi-blade impeller and a special cutting device. Radial
cutter and cutter ring protects clogging of the pump by matter type incontinency and hygienic pads, tampons,
plastic bags, textiles and disposable wipes etc. Cutting device effectively grings-up all these matters and
allows continual and long-time operation of the pumps.
4.0.8
L – industrial pumps fitted with axial or diagonal bronze impeller.
WD detector (AF and cast iron AL series - output 1,5kW and more)
WD detector
is conductor placed in oil bath of mechanical sealing and insulated from frame of the pump. WD
detector has two used wires – one from insulated conductor and second yellow-green coloured on
grounding(frame). If water leaks to the oil bath the WD detector may signalizing or switch off the pump
(depend on protection conected to WD).
Electric motor constitutes a single assembly with the pump. The rotor has an extended shaft for fitting the
impeller, eventually radial cutter (GF) or agitator (AG). It is supported on bearings lubricated by grease. The
service life of the grease refill of the bearings is identical with the service life of the bearings. The hydraulic
part of the pump and the electric motor is separated by double mechanical sealing greased and cooled by oil .
The water side of the sealing is fitted with additional gufero sealing. A little pollution of the liquid by the refill oil
cannot be excluded (e.g. in case of worn seal).
The supply cable (eventually WD detector cable) terminates from the upper cover area with a cable base
sealed in upper cover to avoid penetration of water. The individual cables are sealed in cable base with a
special resin to prevent from penetration of water.
