Slurry Pumps & Valves for Mining & Dredging

Slurry pumps, dredge pumps, slurry knife gate valves and crusher wear parts for mining and dredging. This page sorts the range by duty: what the pump or valve has to pass, at what head, and how abrasive the solids are. Every size, head and material below is read from the product data, and each card opens the full parameter tables for the lead model.

Materials & standards

What each series is cast or lined in, and the standards and data its dimensions come from.

Dredging & Sand Pumps

Read from Dredging & Sand Pump (NJB) — NJB · 19 models · DN120–700

BodyHigh-chrome alloy (Cr27) / rubber lined, replaceable

The table below is the published rating point per model. Solids concentration, maximum particle size and wear-part grade are confirmed per application.

Slurry Pumps for Mill Discharge & Tailings

Read from Heavy-Duty Slurry Pump (KSH / KSM) — KSH · KSM · DN20–650

Wetted PartsWear-resistant metal (high-chrome alloy) or rubber lining
CasingDouble casing — outer casing carries the pressure, inner liner carries the wear
ImpellerWear-resistant metal or rubber, matched to the liner
ShaftHigh-strength steel with replaceable shaft sleeve
Bearing FrameGrease or oil lubricated, replaceable as an assembly

Ranges are for preliminary selection; the final model is chosen against the duty point and the printed H-Q curve.

Gravel & Sump Pumps

Read from Gravel Pump (KSG) — KSG · DN100–400

Wetted PartsHard wear-resistant metal (high-chrome alloy)
CasingWide single casing with clamp-band joint for large solids
ImpellerLarge-passage hard metal impeller
ShaftHigh-strength steel with replaceable shaft sleeve
Bearing FrameGrease or oil lubricated, replaceable as an assembly

Ranges are for preliminary selection; the final model is chosen against the duty point and the printed H-Q curve.

Slurry Knife Gate Valves

Read from Slurry Knife Gate Valve — KPZ73 · DN50–DN1000

BodyCast iron / carbon steel / stainless steel / duplex steel
GatePrecision-machined knife gate, guided inside the cavity
SeatReplaceable resilient rubber seat — NR or EPDM
Body ConstructionTwo-piece split body, machined for a gap-free cavity
Stem SealingMoulded packing with a dedicated upper seal
DrainRecessed bottom drain cover for flushing

What we need to quote

A pump or a lined valve is quoted against the duty point, not off a catalogue page. Send these and the reply is a model with its curve, not a range.

  1. 01Flow rate (m³/h) and head (m) at the duty point
  2. 02Solids concentration and maximum particle size
  3. 03Liner choice — high-chrome (Cr27) or rubber lined
  4. 04Line size and flange drilling, if the pump replaces an existing unit
